Invalid VIN/OS Pair Message, HELP PLEASE

[svaras]

Hi, maybe I can get some help here... I will try to resume.

1) I connected a PCM (E38) and read the file. It asked me to get a license which I did, saved, no problem. The Info said that the PCM was from a 2013 Silverado.
2) To make a test, I uploaded a 2008 file via a write entire. It worked.
3) Now I want to make a new write entire (with the right file I will use), and I got this message: "Invalid VIN/OS Pair".
4) So I tried to make a read entire and it ask me to insert a VIN. If I write the original VIN from the Silverado it starts downloading the file. After is done, it ask me again to get a license, I press ok, and gave the same "Invalid License/OS Pair" message.

Any clue ??

You corrupted the ECM. Operating systems aren't interchangeable. Writing a 2008 file to a 2010+ E38 sealed that thing's fate.
