programmstart with edb error

[Solea-AG]

Hallo,

my AutoCAD Civil 3D 2010 starts with an Errormessage, unknown file format C:\ProgramData\Autodesk\C3D 2010\deu\Survey\Beispiel.edb.

Next i klick ok and another, same message pops up with  C:\ProgramData\Autodesk\C3D 2010\deu\Survey\Beispiel.fdb.

All files exists and user has permission on it. Autocad run on Win 7 64bit SP1 untill jesterday.

Because of startproblems we execute the programrepair routine. Now AutoCAD start with obove mentioned problems.

Thanks for help,

Tom
