looks like a DB connection problem. tripple check your DB's host (127.0.0.1 ?) login, and password settings. . . No really. Check them!! (hehe) If that is all correct, did you populate the database "eq" with the stuff listed in the "how to set up a server" forum? Check the DB tables and make sure they are there and not corrupted.
Option 2: Start over from scratch
