I think GRC is right and the problem is that the OP is trying to upload the ffp file instead of the torrent file. You should copy/paste the ffp file in the box at the bottom of the upload page and upload the torrent file you created (manage atachments), then hit submit new thread, download the torrent file from the thread just created, point it to the appropiate folder and start seeding.

For audio uploads you should create ffp's or st5's, no md5's are allowed for audio.
