Maybe you're having a problem connecting to the right DB.
Try making the little console mode program I posted in this thread and tell me if it works.
Use the same connction string for this that you are using in your .config files for ThePhile.
This just lists the names of the users in the table Accounts_Users.
If this works, then your connction string is good and your DB looks readable.
This will help us narrow down the problem.
