I am unable to upload mp3 files to Sibelius. Sibelius, my isp, and Norton have so far provided nothing useful. I can not verify that the problem is only Sibelius, since I don't upload elsewhere. I restored my system with Norton, using a backup taken on 21 January 2006, which was 2 days before the last 2 successful uploads. That seems to take my system out of the problem, but as a check, can anyone offer a place for me to upload 1 mp3, which need only be there until the upload is confirmed? My site is still on the drawing board, so I can't try that.
