System.Login error with version 6 but not version 7

[RobW]

I have been using version 6 for sometime and have recently hit a problem with one particular database where I get the System.Login error when trying to connect.

I have downloaded version 7 (trial version) and am able to connect without this error (with the same username/password), but as soon as I go back to version 6 I get the error again.

Any ideas?

You probably have an empty sys.plsqldev_authorization table in this database. You need to drop it to get access with 6.0.
