Is it somthing like this?
The process 'C:\Program Files\AutoCAD Civil 3D 2008\acad.exe' (as user... ) attempted to access a resource which would have resulted in the user being asked the following question. 'The process C:\Program Files\AutoCAD Civil 3D 2008\acad.exe is attempting to invoke a system function from a buffer. Do you wish to allow this?'
Or something else...?
