Music products fields are empty on loading an existing product

[jaheadlee]

When I try to edit music products, the existing data does not load except for CEON URI. I don't know how long this has been true, since I just noticed it yesterday and haven't recently made any changes to the code. This problem occurs ONLY with music product types -- the other two product types I use are general and book. I thought perhaps the addition of the CEON mod had gone wrong in the music php file, so I reverted to the pre-mod file, but the same problem exists.

I did a search on the forum and found several suggestions, all of which led me nowhere. CHARSET is utf-8 in all files, catalog and admin. No special/weird characters in product descriptions. It seems that whatever passes the prodID to product_music.php is not passing it, since the array is empty thus never entering the "new_product" case, although strangely enough, it knows enough to fill in the URI mapping field.

So, where do I look next? I attach my product_music.php file, even though I don't know if the problem is in here just in case.

The error message I generate when I try to edit existing records is:
