Activate the Console
Choose Tools > Error Console. If you already use Firebug, then you can use it's "Console" tab as well.
Instructions vary from version to version. If you can use a different browser just for this test, we'd really appreciate it.
From the Opera menu, choose Page > Developer Tools > Error Console.
With your console active, enter your Passpack account, and do whatever it was that didn't work the first time. Or if your support rep gave you specific tasks, then follow those instructions. When you're done, or if you get stuck, check the console to see if any errors were reported. Copy and paste these to your support rep. Thanks!
