First off lemme say this is one awesome patch. I started a season with Arsenal.
You are allowed to change IGM, lineup for ONE team right?
I know everything is perfect in the game but I had to change the IGM and lineup to the way I like it. So i changed some reserves to subs and i had to play around with that cuz when I actually played a game and wanted to sub. The list seemed like it hardly changed.
Anyway that didnt matter all to much to me.
Got the guy i wanted in. Just a striker.
starting lineup remained how u guys put it.
The problem I have now is that my defender got a red card in a previous game and so when i try to play my next game it just goes to my desktop. I tried all the reserves and subs to play for him but to no avail,there is no solving this.
I reseted the team and still nothing.

I hope you can provide me with a solution.
it would be pretty whack if i cant play cuz the roster was changed by a red card.

Perhaps its not the red card.It might be the stadium that you play in for that match. Find out who you play against, what stadium they use, if its a home or away game? Try playing the same teams in a friendly with the home team and the away team accurate and see if it's the problem.

If this doesn't solve the problem it might be a roster conflict. From playing another patch, I found out that the custom.db file created when you customize a player or a team, will cause a patch to crash. This may not be your problem though.
