Symantec DLO 7.0 console is not opening...

Hi,

For one of my client, we migrate Backup Exec 2010 DLO to Symantec DLO 7.0

its worked fine for some time, after that its very slow to backup data to storage location and also its very slow to open Symantec DLO 7.0 console, after few days, Symantec DLO console 7.0 is not opening, so we opened case with symantec, they ask us to reinstall Symantec DLO 7.0 and recover database.

can anyone how to reconfigure exisitng database with Symantec DLO 7.0.

means, how to recover existinf database with new Symantec DLO 7.0 with same server.

Thank you.
