*** Fatal Error: Access Violation at 0X0000000000375A98

[Altera_Forum]

Any one can help me resolve this error. It happened when I uncheck a line in report windows in chip planner. 

How to contact to Altera? How long do you think they'll fix it? This 's the 4th error I've seen in Quartus II 12.1 SP1, which I have just installed to night. It makes me crazy.   *** Fatal Error: Access Violation at 0X0000000000375A98 Module: quartus.exe Lock in use: 12 Stack Trace:  0x55a97: MEM_SEGMENT_INTERNAL::s_segment_heap + 0x215bf (ccl_mem)  0x1305b: APEQ_MODEL_MANAGER::insert_node_data + 0x15b (ACE_APEQ_MODEL)  0x1477a: APEQ_MODEL_MANAGER::build_node_selection_map + 0x15a (ACE_APEQ_MODEL)  0x1772f: APEQ_NODE_PROPERTY_DOCK_WIDGET::changing_node_property + 0xb2df (ACE_APEQ)  0x17923: APEQ_LITE_WIDGET::construct_apeq_lite_widget + 0x53 (ACE_APEQ)  0x5026f: ace_acvq_create_frame_wnd_exported + 0x2075f (ACE_ACVQ_ACVQV)  0x5050d: ace_acvq_create_frame_wnd_exported + 0x209fd (ACE_ACVQ_ACVQV)  0x1111ec: QMetaObject::activate + 0x35c (QtCore4)  0x376916: QComboBox::initStyleOption + 0x566 (QtGui4)  0x376c49: QComboBox::initStyleOption + 0x899 (QtGui4)  0x377da1: QComboBox::setCurrentIndex + 0x61 (QtGui4)  0x37a0d3: QComboBox::setModelColumn + 0x313 (QtGui4)  0x37bf91: QComboBox::qt_metacall + 0x211 (QtGui4)  0x1111ec: QMetaObject::activate + 0x35c (QtCore4)  0x1544b0: QAbstractItemModel::rowsInserted + 0x40 (QtCore4)  0xf84ca: QAbstractItemModel::endInsertRows + 0x5a (QtCore4)  0x515e15: QStandardItemModel::insertColumn + 0x335 (QtGui4)  0x515ed0: QStandardItem::insertRows + 0x10 (QtGui4)  0x37ace2: QComboBox::insertItems + 0x192 (QtGui4)  0x4e586: ace_acvq_create_frame_wnd_exported + 0x1ea76 (ACE_ACVQ_ACVQV)  0x4e7f1: ace_acvq_create_frame_wnd_exported + 0x1ece1 (ACE_ACVQ_ACVQV)  0x2cd2a: ACVQV_FRAME_WND::connect_signals_to_ctrl_slots + 0x690a (ACE_ACVQ_ACVQV)  0xa1612: mdb_dyn_get_ip_regen_dlg + 0x3c362 (sys_mdb)  0x33104: ACVQ_CTRL_IFC_FOR_VIEW::metaObject + 0x10c64 (ACE_ACVQ_ACVQC)  0x1104e: TclEvalObjvInternal + 0x32e (tcl85)  0x596af: TclExecuteByteCode + 0xf9f (tcl85)  0xa7e53: TclObjInterpProcCore + 0x73 (tcl85)  0x1104e: TclEvalObjvInternal + 0x32e (tcl85)  0x11f2b: TclEvalEx + 0x88b (tcl85)  0x126a9: Tcl_Eval + 0x29 (tcl85)  0x6d60: atcl_tcl_eval + 0x100 (ccl_atcl)  0x1e164: Acvq_Unload + 0x18c74 (ACE_ACVQ_ACVQC)  0xf607: TclInvokeStringCommand + 0xc7 (tcl85)  0x1104e: TclEvalObjvInternal + 0x32e (tcl85)  0x11f2b: TclEvalEx + 0x88b (tcl85)  0x126a9: Tcl_Eval + 0x29 (tcl85)  0x6d60: atcl_tcl_eval + 0x100 (ccl_atcl)  0x68fe9: ace_acvq_create_frame_wnd_exported + 0x394d9 (ACE_ACVQ_ACVQV)  0x69dfe: ace_acvq_create_frame_wnd_exported + 0x3a2ee (ACE_ACVQ_ACVQV)  0x494809: QAbstractItemView::qt_metacall + 0x229 (QtGui4)  0x4d28c0: QTreeView::qt_metacall + 0x20 (QtGui4)  0x3e021: AFCQ_TREE_VIEW::qt_metacall + 0x21 (GCL_AFCQ)  0x367c1: RPWQ_REPORT_TOC_VIEW::qt_metacall + 0x21 (resr_rpwq)  0x69ec1: ace_acvq_create_frame_wnd_exported + 0x3a3b1 (ACE_ACVQ_ACVQV)  0x1111ec: QMetaObject::activate + 0x35c (QtCore4)  0x4dc0bd: QItemSelectionModel::emitSelectionChanged + 0x69d (QtGui4)  0x4de426: QItemSelectionModel::select + 0x3e6 (QtGui4)  0x4cef57: QTreeView::rowHeight + 0x1907 (QtGui4)  0x4cf996: QTreeView::setSelection + 0x3c6 (QtGui4)  0x492be1: QAbstractItemView::mousePressEvent + 0x461 (QtGui4)  0x4d19ce: QTreeView::mousePressEvent + 0x6e (QtGui4)  0x6cd46: QWidget::event + 0xb6 (QtGui4)  0x39e896: QFrame::event + 0x36 (QtGui4)  0x4926ae: QAbstractItemView::viewportEvent + 0x5ce (QtGui4)  0xfc622: QCoreApplicationPrivate::sendThroughObjectEventFilters + 0x82 (QtCore4)  0x2008d: QApplicationPrivate::notify_helper + 0xed (QtGui4)  0x22182: QApplication::notify + 0x7e2 (QtGui4)  0xfc4b0: QCoreApplication::notifyInternal + 0x70 (QtCore4)  0x21602: QApplicationPrivate::sendMouseEvent + 0x1e2 (QtGui4)  0x84215: QApplication::winFocus + 0xe25 (QtGui4)  0x86f25: QApplication::restoreOverrideCursor + 0xbe5 (QtGui4)  0x171d: DispatchMessageW + 0x1fd (USER32)  0x14d6: MsgWaitForMultipleObjectsEx + 0x236 (USER32)  0x123eb4: QEventDispatcherWin32::processEvents + 0x544 (QtCore4)  0x86294: QApplicationPrivate::translateTouchEvent + 0x824 (QtGui4)  0xfbab0: QEventLoop::exec + 0x150 (QtCore4)  0xffedf: QCoreApplication::exec + 0xdf (QtCore4)    0x4e88: msg_exe_fini + 0x58 (CCL_MSG)  0x56cc: msg_exe_fini + 0x89c (CCL_MSG)  0x1614: MEM_SEGMENT_INTERNAL::~MEM_SEGMENT_INTERNAL + 0x1a4 (ccl_mem)  0x62ff: msg_exe_main + 0x8f (CCL_MSG)      0x167d: BaseThreadInitThunk + 0x19 (KERNEL32)  0x1c3f0: RtlUserThreadStart + 0x20 (ntdll)   End-trace   Quartus II 64-Bit Version 12.1 Build 243 01/31/2013 SJ Full Version Service Pack Installed: 1
