Youtube just stopped working

view story

http://forum.xda-developers.com – I was on CM10 but restored to my old Hydra ICS. Youtube worked perfectly fine until yesterday, for no reason (as it was working earlier in the day) it wouldn't play any videos. I get this message: This was a problem while playing. Touch to retry". I uninstalled, reinstalled via Google Play. And I also installed with a custom APK from this forum (to enable HD), still doesn't work. However, if I use Super Video, the video plays no problem. Any ideas on how I can fix this without going to a different ROM? (HowTos)
