Hello!
I have a question, please give me help!
I and my brother are playing football manager 2011 online with hamachi!
I”am Arsenal manager, and he is Manchester United but we want to manage 1 team ...
... We want to create a team, and he and I are the managers! But I don”t want to play 1 hour exit, and after he 1 hour ... we want to be 2 in the time!
How to do this?

Simple: You can't.

And:
If I play with Man.Utd first team and he is play with Man Utd (B) reserves team?

I don't think so because he'd have to be your Ass Man and you can't offer such contract to another human player.

Who knows, maybe someday SI will make a game called Assistant Manager. (H)

We edit 2 teams (West Ham - Wigan Athletic) and we put Wigan to West Ham”s afiliated clubs, but when we want to create the game we have an error from the xml file...why?
An error with qualification system..because we put that West Ham finish last year on the 2th postiton?

Stop messing around with it!

Your best bet for this stuff is the Sports Interactive forums.
Guessing that the game crashed as I don't think you can have a feeder club on the same division

You can do this with Spanish teams if you load up a league where their B team plays. For example one of you can play as Barca and the other as Barca B team in the second division. Note that the B team is not allowed to go to first division even if they win the league.

The English affiliate problem you have might be because you can't be affiliated to a team in the same division. It would create too much conflict of interest. I know Serie A used to have it (Inter and Chievo) but I don't know if its there anymore.

Playing as Juventus I still have Siena as an affiliate in Serie A, so yeah, it's still there.

Isn't it possible that you get the error because your database is different? You didn't send the xml file you made with the editor to your brother maybe.

I get this error when I want to play single game!
But I think my problem is because I change West Ham last year league postition to 1 (because I want to play in U.C.L) but I don”t change Manchester United position 1!

Well that's quite the conundrum.

In past FMs when I had to change euro qualifications I had to go somewhere in club setting and give them a qualification place (I would have to chose third round, group stage etc) and then erase it from another team.
