Same Problem here…me and two other friends bought the game earlier. Two days ago another friend of us bought the game too. Me and the other two guys have version 27374, but our fiend who downloaded the game as the last of us has version 28218 right now…so it is not possible to find each other in the lobby browser. All options we should have to download the game doesnt work at all. Are there any guys with the same problems or solutions? 
Thanks
