webmail internel server error

[slayer1ss]

right now i m using plesk 8.6 on a windows server 2008 enterprise edition and my problem is that whenever i try to enter webmail i get 500 internal server error( you can see at http://webmail.godaddy.com.tr/ )... i looked at forums and tried several things to fix this ( including that 2 commands which fixes webmail installation - one of them gave an error as something like file not found ) i m really stuck right now and i need help
