Well, I have been using the same V2 on one truck for almost two years now. It has always been up to date and I use 7.5 to tune and flash both my PCM and TCM. This is on a 2005 Duramax, LLY. So, today, I tried to do a full reflash with DSP5 tuning, not the first time I have dont DSP5 tuning.

The issue is when I go to flash the truck, it tells me I have to go to V2 VIN Lisensing. When I open the software on my computer, it doesn't show the V2 being attached to, or even having any lisenses left. But, if I open up just the V2 plugged into the truck, it shows both my PCM and TCM uses. I am at a loss and not sure what to do. Any help would be great!
