i've tried 1 thing which helped my brother take your hard disk open a new pc plug in the hard disk, Format you whole Disk install windows on it install GRP on your pc that you put in the hard disk and try to login if GRP works take your disk back to you pc if this aint working than i suggest you to download a new windows on an USB or Extern Hard disk and install the game.I got it fixed but i'm not playing it because such a game is not worth any of my time i fixed this to get to the bottom of it because alot of people said they are banning your Hard disk. I hope i helped you out.
