We are setting up a new Drupal 5 site. We implemented the Account Types module. We created a bunch of account types, but we can't seem to assign roles to users, we keep getting an error message "failed to delete invalid roles upon account type update" and "account type update was unsuccessful" and it will not allow any roles to be added to a user or allow the account type to be anything but "basic" even though we have set up both roles and account types. Any ideas?
