Hi Stephen I used the Crypton service many years ago when I started with diagnostics and found them very helpful at first. The chaps on the phone gave me some good pointers and where very easy to deal with. But it didn't take long before I got to the point that they couldn't help me as I was doing all the basic checks before I phoned them and then after chatting to them and them saying they could not help. They did say that when I sorted the problem could I ring them back so they could note down the fix and help others I cancelled my subscription. I now do training instead
