Problem starting OPManger

Hi,

I have a problem starting OPManager version 7. Here are some portions of a log file:

Checking for the availablity of the Primary Server in the Database. Found an entry.

Trying to connect to the Primary Server at 192.168.0.18. This may take 4 seconds.

Please wait .
.
.
No response from the Primary Server as it may not be running. Unable to connect.
Primary Server may not have been properly shutdown in the last run, resulting in the Database not being properly updated.
Starting up as Primary Server and correcting the Server information in the Database.

Starting AdventNet ManageEngine Server Modules, please wait
Process : DBServer [ FAILED ]

Process : OpManagerStatusProcess [ Started ]
Process : AuthMgr [ Started ]
Process : DataMgmtRPI [ Started ]
Process : NmsPolicyMgr [ Started ]
Process : OpManagerRunApacheExeModule [ Started ]

Process : CLIFactoryBinder [ Started ]
Process : SetSecurityProperty [ Started ]
Process : NmsTftpServer [ Started ]
Process : NMSSAServer [ Started ]
Process : StartTelnetClient [ Started ]
Process : RunJSPModule [ Started ]

I tried running repairdb (repairdb finishes with no errors, just warnings about not properly closed tabels), and starting OPManager service again but with no success.

I tried starting mysql through CMD (startmysql) but nothing happens, CMD window freezes, although I can see mysqld-nt.exe process has started. Stoping a mysql (mysqlstop) successfuly stops a process mysqld-nt.exe.

Can anyone help me....this is second time this has happened to me. How can I reinstall OPManager with previous configuration? I havent done any backups:(

Thanks
