I've frequently crashes of my rf2. here is what the windows event protocol says (Google translation from german windows7 version) Log Name: Application Source: Application Error Date: 04/12/2013 17:26:01 Event ID: 1000 Task Category: (100) Level: Error Keywords: Classic User: Not applicable Computer: Nor-PC Description: Name of misapplication: rFactor2.exe, version: 1.3.4.2, time stamp: 0x5266c2dc Name of the faulty module: ntdll.dll, version: 6.1.7601.18247, time stamp: 0x521ea8e7 Exception code: 0xc0000005 Error offset: 0x00038e19 ID of the faulty process: 0xf24 Start time of misapplication: 0x01cef10a6487f3a7 Path of misapplication: d: \ rFactor neu2 \ Core \ rFactor2.exe Path of the faulty module: C: \ Windows \ SysWOW64 \ ntdll.dll Report ID: c2e99c08-5d00-11e3-B27E-e31b0983e682 So the ntdll.dll is causing the problem, what does the ntdll.dll do with rfactor? Maybe I should also mention, that another event error protocol sais that d3d9.dll ( in rfactor2/core folder) is causing rf2 crash. This file belongs to the trackmap plugin. I guess when I remove the plugin the second crash cause is solved. Does the ntdll.dll has also something to do with plugins? Thanks in advance Norbert
