hey keeper, i have having the same darn problem now.... i had my lies and team working,,.. i bought a pack of cards and received a bobby ryan, which i flipped for 30,000 and started buying guys i wanted to have on my team... i think when i somehow sent all the used players and free-bees either to the trade pile or the quick sell option, i somehow maybe undressed my backup goalie... i dont know where to dress them, for there is only one goalie spot, all my lines and cards are compadible, for i removed them all, and added them all too... i dont have any duplicates on the same lines, and i get the exact error message u are getting... i somehow went from 4+ stars to the same 2.5 stars u are seeing, yet all my players got better and chemistry is emacculate now, but i still cant play.... i think it has to do with our goalie, and that we dont have a backup dressed, but im not sure how to dress one, i have 5 in my scratched spot on my roster, and u would think the darn game could auto assist lines that arent valid to ones that were.... from a very frustrated canck! lol
