it's freezing when I'm simulating games in april in dynasty

[costaga]

I know it's not a new problem for you guys but it really bothered me. I followed the right way (sticky threads) to install the MVP and updated to 07mod with KG roster. It seemed fine in everything. I can play any game in exhibition and dynasty mode. But when I added my favorable teams to KG roster with some adjustment in free agents, I got freezes at simulating games in dynasty mode at about April 15 to 20. But I still can play any game in exhibition mode. I know it should be a roster problem but I still have no idea about fixing it. I used MVPedit 2006.2 to edit my adjustment. And I also checked all my lineups and rotations are correct. Could someone please give me any advice? I really love this game but I can't play it because of this freeze. Thanks!
