I cannot upload audio files.
the applet downlaoded successfully, it first ask for me login and password, then I press “Select” button and mention the file I want to upload, then I clicked on the “Upload” button. I got the message that if I clicked on “Yes” it mean I agree to the terms. I clicked “Yes”. And thats it, I waited and waited and waited but nothing happened. 
Please send an email to [email protected] for a quicker resolution. There was also a FAW thread in Audio Gallery. See if you can search for it and whether it helps resolve your issue.
