Please Help me!!!!! I have a problem that is a consequence of the upgrade that I did from plesk 7.5.4 to 7.5.5. It does not allow me to access the control panel. The error that it shows is as follow: "Fatal error: Unable to open key (SOFTWARE\Plesk\PSA Config\PSA Key): (5) Access is denied. in C:\Program Files\SWsoft\Plesk\admin\plib\common_func.php3 on line 2346" Does somebody know what is happening?
