Part 2: How to Solve GM MDI2 Not Connected to MDI Problem

I bought the GM MDI 2 package from OBD2 last week. I installed the MDI Manager software along with HDD but when I tried to connect the MDI device it asked me to recover the MDI software because the one is out of date. So when I try to update the GM MDI device an error occurs every time. And at the end, after a few seconds the device automatically disconnects and I can do nothing with it. I cannot connect again and the device seems dead.

I made several attempts to update/recover the MDI device but with no luck.
