Please help me, I bought the game on steam right then i got an account. But them it said The game has not been activated
Yeah a few people have had this the last few days..... Your best option is to contact support@uberent.com and they can sort it out for you. You wont get a response until a bit later on though due to time difference.
Just link your Uber account to Steam: https://uberent.com/user/linksteam Once it's done game will work fine.
