I'm not sure what happened, or when, but it seems like the 'psa' database got severely corrupted. I'm missing my .MYI and .MYD mysql files for Plesk. Is there anything I can do to get plesk back up and working without starting from scratch? I have 30 customers who are now unable to check mail, log in, etc.

I'd greatly appreciate any help.

Problem solved, I had disabled innodb databases in my my.cnf. Commented out that line, restarted mysql, everything is well.
