mkr17: how can i check which patch i am using
If you haven't manually installed the 1.1 patch, then you're running 1.0.
But if you want to check, you can go into Program Files, then get into the game directory (which I assume is different based on the different versions, but mine is in the "GOG.com" folder), go into the "bin" subfolder and hover your mouse over the witcher2.exe file. If it says anything other than 1.2.abunchofrandomnumbers, then that save file won't work.
What version of the game do you have? GOG version or something else?
