Alright guys I got one for you that stumped everyone on PBcity. I went to change the ROF on my Excal. I followed the instructions to a tee. When it came time to program the gun I got a <run-time error 53> anyone got any clues. I also gave my gun and cable and instructions to my brother who is an engineer and works with computers everyday and he got the same thing. I haven't had a chance to call AKA yet so if anyone has any ideas I would be greatly appreciative.
