I ended up on the phone with tech support & well, of course it couldn't be as simple as just an update. It needed to have a global reset & the pedal calibrated & all of that good stuff. I did lose my only patch I had started working on, BUT I do know now to save them in case I need to do a whole reset again. I have a feeling that with the way it's set up, I will have to again in the future.
I don't have a million patches, BUT the few I have created are VERY workable in almost every type of song. This flash update problem on the HD500 & re-setting everything seems to be the only issue I have. I LOVE this thing!!
Problem....SOLVED :)
