Hello there, I'm having some troubles right after the 2.62 firmware update. (I did it today, the previous version was 1.30 I guess) My POD HD 500 doesn't work anymore, and everything was ok before the update. I tried to downgrade , but there is a communication error between the POD and the computer that wasn't there before. if I connect the pod on power and select any set, it crashes. And if I turn the Tunner on, a strange sound appears when I play he chords, and when I press any FS button, it crashes. Please, I need some help!
