unable to login into my site after a snapshot restore.

I did a restore of a backup that I created with snapshot and then I wasn't able to log into my website after that.
I contacted Bluehost and they told me it had something to do with the tables and that they could not fix the problem.
Would you tell me if you could log into my account and see if you can figure out what the problem is and let me know what I can do to keep from having the problem again the next time that I try to restore a backup with snapshot?
