New installation of Opmanager with (external) MS-SQL databas

After my new installation of Opmanager with a (external) MS-SQL database i have the following error in my webinterface.

Oops looks like a few tables got corrupted. Don't worry.. Run RepairDB.bat from bin directory and restart the server.

I tried the repairdb.bat buth then i get:

myisamchk: error: 22 when opening MyISAM-table '..\mysql\data\OpManagerDB\*.MYI'

myisamchk: error: 22 when opening MyISAM-table '..\mysql\data\OpManagerDB\*.MYI'

Press any key to continue . . .

After that i rebooted the server buth still i got the same error. It looks strange for me causse it looks like it gonna update the MYSQL database buth i use a MS-SQL on a other server.

N.A. on the same machine i also run Application Manager!

Please advise
