Yesterday I did a full read and pulled the stock file from my buddy's 2011 Silverado 5.3L/6A. I brought it in my house, did a "Save As" which asked me to license it. I bought 2 new credits, spent them and wrote the tune myself from scratch.
Today I plugged into his truck to upload the tune and it shows "unlicensed," can't even load the stock tune. I have resynced my interface and restarted my laptop. If I have to buy more credits, I'm going to f#%$ing scream because it will kill almost all my profit.
I searched through half a dozen "unlicensed error" threads but they all had more obvious issues like using a different interface or using someone else's licensed file.
