Please note that everyone that sent us the GOG version of the exe, the game is STILL at the 1.1 level and you should be using the 1.1 trainer. Trying to use the 1.2 trainer will crash the game until the actual patch is applied.
I have the GOG version, checked version history on witcher2.exe and it matches that of the new 1.2 trainer, so it would appear that they merged the versions together, or at least that's how it looks to me...I'm more then willing to submit the file if you'd like :P
keep up the awesome work
