I don't know how it happened, but my Zune is stuck on lock.
Before anyone assumes that the switch is stuck in the lock position, it isn't. I can move the switch between lock and unlock as I wish, but it will do nothing - the Zune stays locked.
Sometimes, somehow, I can play / pause / view song lists, but then it will go back to being stuck in lock and I can't do a thing with it.
80GB Zune, if there's anything about the size that makes a difference.
Thanks!
