Katherine, You don't mention if you're using a Mac or PC based computer. There is a known problem with Mac that I can help you with. The same process may work with the PC, but I haven't tested it. Can you post details about your device?

It tells me "a required file is broken" and gives me an error code 1003. I have uninstalled and then re-installed the software and it still won't open up. Any thoughts?
