ALDL cable problems

I've recently programmed an email tune to my 95 Z28 without any problems using Winflash. I downloaded Datamaster today and when I'm trying to datalog it says no PCM communication. I also tried to read the tune with Winflash it says cable is good but will not communicate with PCM. Any ideas what could be wrong?
