Please Help: Database missing files

I had to restore my database from a server backup and my host tells me that from the way database files are stored by default, two tables connected to Ray Chat are missing and cannot be recovered.

Error    : Table 'dolp860.RayChatMemberships' doesn't exist
status   : Operation failed dolp860.RayChatMembershipsSettings
Error    : Table 'dolp860.RayChatMembershipsSettings' doesn't exist
status   : Operation failed

Each table contains 3 files, and some files regarding this tables are missing.  The only help they could give me was a recommendation to contact Boonex to see if there is a way to rebuild the database with these files missing.  They said that the db cannot be dumped in its current state.

Has anyone experienced this issue or have any idea what I can do to at least repair the db so that it can be dumped?

I'm still experiencing this issue.  It seems that users are having other  users' pictures posted to their accounts and vice-versa.  The only option I know of is to start over with a new db.  Please tell me there's some other way.
