CDR Database Problem

[Casta]

I have got a problem with CDR, more exactly with the database.
When I want a reports ( User System or device ), I have always the same error message :

-30061 : data is not available in the database.

détail:
Code error: 1012
user message: Data not available for the entire date range of the report.
Program name: CtrPregenReports[generate]
User: Schedule


Before purging the database, the reporting was available but between 09/1970 and 10/2001.
After purging the database, I have the error.

I 'm looking for the solution, but I need a help.
Thanks.
