I'm having problems uploading. Basically really small mp3 that are under 1mb seem to upload but the larger ones don't work. The progress bar keep resetting back to 0%. Sometimes it does this a few times then completes the upload but hangs at "Crunching". I really need some help as I am setting up a music site and need this to work. My max file size limit is currently at 7mb and the files im trying to upload vary from 4 to 6mb.
