iReport Creating a new Database

I currently have iReport working on my computer, under my username, but when I switched users and tried to reset up iReports and rebuild the database connection (I built it the exact same way as the other one) I'm getting an error saying it's having trouble opening it and it's "Null"

Do I have to set them up differently for it to work? Can i have the same connection on two different users and it work? I've done everything thing the exact same- including the server IP and Fishbowl file location.

Please help. Thanks!
