Navision 2015 (Backup / Restore) Company

I have a problem on importing NavData Backup into Database.

Situation. Client has 3 DataBases because he has a lot of Companies in the Database. It is a historical relict, because in old Navision Backup need a real long time to restore a company or delete a company. Now i have 2015 working (Back to Basics) with smale modifications.

If i export a company i am not able to import the backup in a other database. I was thinking it is a structure problem. For this i made a test to import into sama database. (Test Comapny was deleted). I am not able to import into same Database.

In Event Viewer i get following Error Message...

Thank you for any suggestions...
