My Ariza 500 is acting up. I have no idea what is wrong with it. I just recently updated it with the newest flash. It works fine for a while then all of a sudden it freezes up then it shuts off and a green dot stays on the receiver. It works fine for a while if I reflash it for a while. Any help on this subject would be appreciated. Thanks in advance.

Zup ultra is working fine install active keys in 3rd line from top to botton and it will work.
