I get an unexpected connection in Crystal Reports instead of the currently logged in database

When setting up a crystal report universal function you have 2 different report source options. You can either set it as "as in report" or "set this database as report source". In your case you would need to set it to the second option because it will then at runtime point it to the correct server/database. Also you will need to inform B1UP with information on how to login to the server. This is done in the Main configuration under Options > set database password.
