Hello, i have Far Cry 2 with Fortunes Pack from gog and after playing single player for 5 hours i wanted to play multiplayer but i had to make a uplay account. After that i went to make an online profile and it asked for a cd key. Where do i get one espically if i have the gog version?

Might be a litte late for a response but the cd key can be found on your game shelf under Far Cry 2 details it's the "My serial number" section
