Ok... updated to latest of 2.24. (I'm assuming its later than what I had)
Went out today to hook it up to my 15 Silverado and lost well over half of the PIDs I was scanning (unsupported is what it says now)
I looked up at top of screen and seen it was on vehicle ID 0.
Then I re-downloaded and installed 2.24 and still have the same problem with PID's not being supported but now it says I am working on a 2014 Silverado. (which I think is what it always said before even though I was on a 2015)
Everything worked fine this morning, no issues and have been scanning this truck off and on for almost 3 months now.
