I had a scanner die on me after about 8 months. I tried everything to make sure I didn't make a mistake, but I ended up sending it back to Alex to test it (after emailing him of course). Not long after a replacement arrived at my doorstep. I just used it to diagnose a CEL on my parents Caravan.
Email Alex. He'll give you some suggestions on getting it working, and if that doesn't work you can ship it back.
