Unable to unlock trophy rep level 50

So, i'm trying to platinum the game nfs heat, 

But i only need one more trophy to unlock, which is the one of rep level 50, 

I've been rep level 50 for a long time now, but the trophy hasn't unlocked yet, i don't know what to do to fix this, I've deleted and reinstalled the game a few times already but that hasn't worked, and so far that I've been searching i haven't found anyone with the same complaint, is there a way to fix this?
