What happens when you try to deposit the checks via image, out of curiosity? I have an account with them too and have never had problems with the uploads, but am expecting a big freelance check later this week.
It looks like they still have the menu option for uploading images... so, is it just erroring out, or "down for maintenance," or ?????
I really hope I do not have to go back to mailing in checks... I had several freelance checks never arrive over there and had to ask my clients to reissue them. Huge PITA.
