I want to take my backup from my PC and play on it on an other PC.
Is this possible ? If yes, can you explain me how to do it please ? 
I dont want to start an other campain ^^
Save files are stored in your windows profile directory - for example, “c:\Users<USERID>\Saved Games”. Move them to the second PC and try to load them
Ok i try immediately
That works ! Thank you a lot
