Registration Code issues for Starry Night Celestron Edition

I've got a registration code, but when I start the Starry Night program and try to enter my optional email, username, and code, the only option I have in the box is to quit. I've tried entering everything and just hitting enter after I've entered the code, but doing this just closes the program. There is a weird outline of the registration pop up box that is off by about a quarter of an inch that I suspect has to do with the issue, but it might just be how the pop up box is supposed to look too.
