[Uplay] Problem Installation Assassin's Creed 3

Hello everyone, I have a problem with Uplay PC. More particularly with AC3. Don't really know if it's the good place for it

I recently uninstalled uplay 'cause it was on my C: drive and it was full. I have a 1To hard drive splited in 3 part, a little 1 (C:) for Windows Stuff (where uplay had himself installed first) and two other part (D: and E:) for video games, movies, musics, etc. But uplay doesn't really like when you just transfer the launcher and the games, don't know why.

So after I've uninstalled all my uplay games and uplay himself, I reinstall uplay on my D: drive. Since I'm doing the Assassin's Creed series all over again, I install AC Brotherhood (the one I was playing) first and Revelations just after.
But now that I'm close to AC Revelation end I tried to download AC3 again but the uplay launcher is considering that the game is installed (like this :http://image.noelshack.com/fichiers/2014/35/1409253009-pb-ac3.png sorry it's in french) But it isn't and I don't have any AC3 files in my computer, so I can't uninstall it again, cause I already did.

All my 8 others uplay games can be downloaded and have been uninstalled perfectly but not the 3.

And I actually asked to the Uplay Costumer Service, but they just told me to delete every single uplay files (even those who are working. And Install it again, they basically told me nothing ecxept the old steam costumer service that only says "Uninstall and Reinstall and if it still don't work f*ck you". Thanks Uplay

Is there a way to make Uplay understand that the game is actually uninstalled and deleted of my computer without uninstall everything ? Cause I'm actually moving on from my house to an appartment this sunday and uninstall and reinstall everything will take forever. And only AC3 doesn't work !

Thanks for those who answer And if it's not the good topic for this question sorry..

Uplay. Not even once.
Uplay might be the worst of every game client. Not sure how to solve there shittyness

Yeah Uplay is the worst game launcher. Even more bugged than Origin. If only they could just use Steam like everybody

Little uptade in case that people have the same problem one day : I did just downloaded a crack of Assassin's Creed 3 and I installed it, without the crack, so when I launch the game it searched for uplay find it, find that I bought the game, and everything is cool

What ? If it's because I'm talking of crack, I didn't crack anything. I did buy the game on xBox 360 and PC I did just take a random way to download the game without using uplay. I'm using a real, paid, version and I will always do it.

Crack Cocaine isn't cool.
