if some one could point me to the program that would get my ariza ultra 500 going I would greatly apperiate it. I had this system for about 2 months and had little diffaculty getting it going before, but it went down a couple of weeks ago and i tried every program i could find but they all seem to be out dated. Is there an up to date program? Do I need a new program every time the numbers change? I even tried putting the new numbers in manualy with no success. are others having the same problem or am I missisng something. thank you for any helpyou may offer.
