I had the exact same problem, my IP was blocked for no apparent reason, but I contacted some FM team members and got it sorted out. That's why you can't access the server or the home page, the IP range or whatever is blocked.
Maybe you can find some active FM members in here that can contact Failure so your IP can be unblocked.
So that's 4 games of the 7 that he played where he helped the team win, not too bad?
He created most changes and completed most dribbles. I don't really get how he could have helped the team with his defending if he clearly isn't meant to do it?
Mascherano was important, but I think Di Maria was even more vital for Argentina.
All in all, Messi couldn't win the World Cup for Argentina by himself. Higuain wasn't really up to par as seen in the final and Agüero seemed out of form. The defence was pretty solid but the attack wasn't. After Di Maria got injured, the team lost a vital link in attack as seen in the following games, they didn't score another goal after that.
I do agree though, Golden Ball to him was rather undeserved. IMO Robben or James would have deserved it more.
