My best friend bought the extended Blu-Ray of LotR and gave me the keys for the digital copy. Not liking iTunes, I redeemed the key (and spent 5 hours) downloading Return of the King. I woke up this morning excited, giddy like a child on Christmas. I opened the Digital Copy Manager and pressed "play." Nothing happened. I figured I'd try opening it in Windows Media Player.
"Windows Media Player blows shit chunks and encountered an error while playing this file."
I jumped through various hoops, tried reloading .dlls, made sure DRMSVC is running, checked all my drivers, used ResetDRM, all to no avail. I figured I'd buckle down and contact customer support, as much as I hate to. So I typed a long and thorough explanation on their website. It froze and closed right before I clicked submit.

TL;DR: Microsoft, get your shit straight, you're terrible at managing DRM, just like you're terrible at everything else.
