Fatal Error

I am getting this error during flights randomly when accessing the menu tabs. I'm using FSX with FSEconomy and Open Clouds. It's strange because I can fly days at a time with out it happening, then might get it two or three flights in a row. Any help would be much appreciated.Problem signature:Problem Event Name: APPCRASHApplication Name: fsx.exeApplication Version: 10.0.61472.0Application Timestamp: 475e17d3Fault Module Name: uiautomationcore.dllFault Module Version: 7.0.0.0Fault Module Timestamp: 4a5bdb1dException Code: c0000005Exception Offset: 0000e52aOS Version: 6.1.7600.2.0.0.768.3Locale ID: 4105Additional information about the problem:LCID: 4105
