login issues

[sindian]

was there an upgrade on the 25th of april? seems my stats stopped working and I can no longer login to the control panel. Get an internal 500 server error. Nothing has been changed on the server. Windows 2003 sp1

an update to the error is this
ERROR: PleskMainDBException
<b>Source:</b> Microsoft JET Database Engine<br/><b>Description:</b> Unrecognized database format 'C:\Program Files\SWsoft\Plesk\admin\db\psa.mdb'.
