When I try and customize the team management of some teams, eg: Notts Forest, I get told that I must reset a team before managing another...what does this mean and is there a way around it?
Does it have anything to do with the potd which I have?

thanks

Yeap, i read that the maker of the PotD made something so that ppl dont mess up the patch. But i think its because he customized a lot of teams (and u know, FIFA lets to to customize only a certain number of teams)
