Hey!
I dont have a problem anymore because everything works fine now but I wanted to report this issue so you guys from Uplay can look into this and prevent this from happening again.
So when you first start Far Cry 3 with Steam, it tells you your Far Cry 3 Deluxe key. But when I started Far Cry 3, Uplay told me in the bottom right corner my key. At first, I didn't notice a differece but after a few years (today, I never got my key working before) I noticed a difference.
While Steam was showing me the actual right key "F3P-DCYN-THF6-UBCA-FQRF"(used already by me, at least I hope so because you cant see if your Deluxe key is active or not), Uplay showed me this: "F3P-DCYN-THF6-UBCA-FORF" WHICH WAS WRONG. The letter "Q" was replaced by an "O". Basically Uplay showed me the wrong key. What kind of joke is that?
But yeah I hope this will never happen again, here are two screenshots from the key in Steam and the key in the ingame-overlay (I guess?):
