I spent several hours rendering and then exporting my first and only video to YouTube only to always get "Error Occurred" on the export screen. There is no explanation for this. After trying 8 times, I resorted to looking on the support page only to see that YouTube isn't working at this time (posted sometime in March). Why don't you just turn off the switch for this until it's fixed? The rendering takes over 30 minutes each time because the video is 16 minutes long. Of course, it isn't working for Facebook either... sorry I spent so much time on this and for upgrading. I never got to use a free export either!
