SBS 2008 Console crashes while generating any report

Hello Experts.
I have a problem with one of my SBS 2008 boxes which I am not able to fix by myself.

Since some days automatic reports are not generated and if i try to generate them manually by clicking 'generate report' link on the SBS console the console crashes with the following error message:

  Betriebsystemversion:      6.0.6002.2.2.0.305.9
  Gebietsschema-ID:      1031

I've searched the web and also the experts exchange website and tried all solutions that are suitabel to my problem without any result.

I have changed nothing on that SBS box. Just the updates were installed and i have renewed the SSL Certificate (as the old one was outdated).

I have tried the following solutions:
- http://technet.microsoft.com/en-us/library/dd560614.aspx
- WSUS cleanup wizzard
- shrink SBSMONITORING log

Thanks for your help in advance!
