problems after upgrading from RC7 to 1.0

[Jibbs]

hi everyone, having a few issues which i need help resolving.

after upgrading my domains work fine, however my control panel login does not

I was getting a 403 forbidden error. After poking around I saw that /var/www/ispcp/gui did not have an index file, so i copied the files from /usr/local/src/ispcp/ispcp-omega-1.0.0/gui into /var/www/ispcp/gui and now i am getting Connection failed: SQLSTATE[28000] [1045] Access denied for user 'root'@'localhost' (using password: YES)

I have not changed any passwords or anything since upgrading. Like i said all my sites and subdomains are working just fine, i just can't login to the ISPCP back end
