Problem with update for Plesk 10.4.4 to 11.5.30

[DanielBr]

Hi Friends!
I need some help.
I tried to update the plesk 10.4.4 to 11.5.3.
When I restart the server (windows Web Server 2008 R2) and try to access the Plesk Control Panel, returns the message "Invalid Signature" only.
What can I do??

Tks.
