Fatal error after upgrade.

[Krisxxx]

Hi
I just upgraded my ispcp from rc4 to rc6. Im running a debian etch server. The problem is now that when i try to enter my admin interface i get this message:

Fatal error: Class 'Config' not found in /var/www/ispcp/gui/include/ispcp-config.php on line 32

When i try to enter the webmail, i get this error:
Parse error: syntax error, unexpected $end in /var/www/ispcp/gui/tools/webmail/plugins/compatibility/functions.php on line 595

During the installation i got a gui error.

What have i done wrong?

Please help me :-/
