Ive only just got around to installing AC3 on Uplay and this is the second time they've given me an invalid code!! The last time was revelations, which i managed to get a replacement code for, I've noticed that its missing a letter at the start, like my copy of revelations, has anyone else had this problem or just me, its really starting to annoy me and if I can't get a replacement, then i will definitely be boycotting their useless service, at least origin are capable of handing out valid codes!
