Oops looks like a few tables got corrupted

Oops looks like a few tables got corrupted

After spending hours setting up op manager and importing all devices, it works ok for a day or so and then get the following error when trying to log in
 
Oops looks like a few tables got corrupted. Don't worry.. Run RepairDB.bat from bin directory and restart the server
 
when we run repairdb.bat it says it finds problems and fixes them.
 
However when logging in we get the same error
 
We have now re-installed op manager 3 times and configured  it.
 
Any idea of the problem? We have disabled antivirus but still get the problem
 
W2K3 server, we have SDP, DC, AD manager running on the same server with none of these problems
