I bet they will. They sent me a new receiver the next day at no charge to test it. Their service is awesome. I don't think there is anything wrong with the cables, but its something in the combination that isn't allowing it to work properly. You may even try another companies mini to mini. If they send you the same cable then the problems might persist.
If they send you one and it doesnt work, send me a pm. I'd be glad to send you one of mine that I know works on my lights. That may help you isolate the problem. Like I said the ones I have are homemade with solder and heat shrink tubing, but they work...that may help you narrow it down.
