Hi,
I'm trying to upload to a Revel account and was not able to reproduce this issue. Could you tell me exactly what you are seeing on Adoberevel.com? When you go to a library or album and click Add Photos or Videos do you see a Browse Library button? What happens when you click it? Can you initiate an upload? is it failing with an error message? Do you have a premium account or a 2GB limit? What browser are you using? Have you tried an other browsers?
If you can let me know the answers to these questions, I hope to be able to trouble shoot this issue.
Thanks for your patience,
Richard
