Not so frustrated anymore - I got a small paint set uploaded (finally!) - woohoo!
Angela at TSR is a godsend. After several days of communication on the forums she was able to determine that the reason why I couldn't submit anything was that Internet Explorer 9 disagrees with TSR's new cloud setup. She recommended I use Firefox. I was hesitant at first, but once I figured out the new layout and got my bookmarks straightened out it was pretty smooth afterwards. Within an hour of installing Firefox I was able to submit my set and work on submitting another set I had sitting on my hard drive.
