unable to load media url
Using Jamroom
It won't help you at all. The key isn't stored with the item.
I think it does work just fine on every other server (apart from yours, obviously). Otherwise people would be posting here saying that their media isn't playing. Keys are being generated just fine on all of mine, I haven't seen any issues with playing media at all, ever.
Why not wait until you get the breaking problems fixed on your server? A reconvert might work better then? At least you could rule one thing out rather than shooting around at a million possibilities at once?
