More RR problems 3rd one died after 30 sec

[minytrker]

My 3rd rr died only after 30 secs. I started my car and played with the idle speeds for about 30sec. Later I tried to mess with it again and got the dreaded cannot communicate with rr. Please tell me Im not the only that is having problems with there's. I tune 6-7 days a week and depend on my stuff to work, so the rr was a great tool to buy because its such a kick ass product. So far my rr has spent more time in the mail back and forth between me and Craig. Anyone else out there gone through this?
I really dont think its my laptop because it done it on both of them. I also dont think its any driver issue or anything because 2 of the 3 rr did work for a few weeks. I hope its something I have set wrong, but I doubt since I have had the rr working already.
