Problem with submitting art supplement?

Hey guys, I was just wondering, does anyone else have a problem with submitting the art supplement through SlideRoom? I’m trying to submit a music file, but when I reach the 3rd page on SlideRoom, the one that asks you to input credit card information for that $10 fee, and I try to click “Next Step -->”, it won’t move on to the next page. It just gives me that loading pinwheel, but never switches to the next page. Furthermore, I can’t ask the UPenn Admissions Office since they’re closed for winter break. Do you guys have any idea what I should do??? Thanks in advance!
