I have recently bought assassin's creed origins from the epic games store as it was discounted and I downloaded it from the epic store (about 47 Go). The problem is that when I try to launch it, it sends me back to uplay and it begins a second and bigger download (about 64 Go). My internet connection is really bad and I already spent 4 full days to do the first download so I don't really want to spend another 6 days downloading the same game. And the first download already took space on my disk so I don't understand. Could someone help me please ?

Thank you.
