problem in psa.misc table

[irlamp]

Hello,

I'm newbie in PLESK.
my plesk is down now,

After we restoring the backups I trying to copy all mysql data from
/olddrive/var/lib/mysql to /var/lib/mysql, so we move exist data to
/root/mysql_back before we copy data.
after we copy mysql data from olddrive to /var/lib/mysql we trying to
copy mysql, horde, psa directory to /var/lib/mysql .
after that we restart mysql and when I trying to login to PLESK show
this error:

ERROR: PleskMainDBException
MySQL query failed: Table 'psa.misc' doesn't exist
