MPEG 4 files won't play!!!

[sarabi_k]

Around the time that Spotify implemented the world's crappiest "update" (you know, the one that got rid of ctrl + f and other awesome features) I was plagued with a problem. Not long after that awful update another was implemented and everything went downhill. I just shrugged it off for a while thinking "Oh it'll get worked out in the next update." Well there's been a next update and I'm still screwed. Today I did everything I could find to fix this problem. I updated iTunes, repaired QuickTime 7, uninstalled and reinstalled Spotify. Here's where it gets interesting. After I uninstalled, rebooted my computer got back on and reinstalled, for just a minute, one sweet and glorious minute, the problem seemed solved. Then it unsolved itself. Why won't my MPEG 4 files play anymore?!?! They played fine a few weeks ago before Spotify did all this update crap. This, plus all the features that have been removed recently is really pushing me back towards iTunes.
