Chuck,
I have always warned everyone that monkeying with the SST (System Status Table) is at best HIGHLY RISKY without having an experienced engineer/tech right beside you to guide you.
Just like being the bomb disposal technician, one wrong move and the entire SST leaves the Aria totally useless. I have never been able to rebuild a "bad" SST.
My experience giving some hard knock lessons here....
Pat
P.S. If you read between the lines of Ken's reply, I believe he and I agree.
