Durametric Won't Connect

[Pirate50]

I would contact Durametric. I purchased a used cable that had a similar issue. They were helpful, they reset the cable by sending me a file if I recall correctly. It was a few years ago, so forgive my memory. Said they would only do this once. I purchased the cable from someone on eBay that said it only used one VIN. When it wouldn't work I thought I bought a counterfeit so I contacted Durametric and they verified it was a legitimate cable. After I told them how I got the cable they told me they could reset it but only once. Now it works fine.
