You can get a lot of information from the error message you are getting. If you can post the error message, I am sure someone out here can help you out; else it would be difficult to debug if there is no database schema to test against.
(to view the exact error message you are getting on IE, go to TOOLS->Internet Options -> Advanced and uncheck "show friendly HTTP error messages")
