ERROR: PleskMainDBException

Hi, after I upgraded to MySQL 5 and upgrading Plesk from 8.1 to 8.2 I can not login to Plesk anymore.

I am getting this error:

ERROR: PleskMainDBException
MySQL query failed: Incorrect information in file: './psa/misc.frm'

db_query(string 'select param, val from misc')

4: /usr/local/psa/admin/plib/common_func.php3:346
db_connect()
5: /usr/local/psa/admin/auto_prepend/auth.php3:87

How can I fix it?
