First of all it takes an obnoxiously long time to start up my xbox. Then every time that I try and sign into my profile, I get a black screen, then it asks me to select an avatar just like when you try to create a new profile. I'm signing into my current one, not creating a new one. I know that my membership is valid because it is not even close to the expiration date.
Never had this problem before the last dashboard update, and I'm really starting to get pretty pissed off over it.
I can't clear my hard drive cache because I can't sign into my freaking profile to do so, I've tried restarting and it does absolutely nothing.
