ClamWin: can't parse new database

Just upgraded to version 0.90.2.
Now I have a problem with updating the database.

The update report mentions the following:
freshclam 0.90.2 (OS: win32, ARCH: x86, CPU: i686)
ClamAV update process started at Mon May 14 13:32:51 2007
main.cvd is up to date (version: 43, sigs: 104500, f-level: 14, builder: sven)
ERROR: Can't parse new database

Anyone a hint how to fix this?

Thanks, Darius
