medal of honor expantionpacks crashes

[noid]

hello and thank you for letting me join the forums,as you all probably can see this is my first post here,so hello again all.

now i got some questions i hope you guys can help out with,as my mohaa games are starting to get old i decided a while back that i would make a backup of em as i love the games and dont wanna ruin them,and use nocd cracks.
this worked out just great until i one day decided to upgrade my os from winxp home to winxp pro.
i have installed the games and patched them and applied the nocd cracks to the directory as i did before,but i only get mohaa to play as it did before?now both expantionpacks crashes when i try to load them,weird thing is that they worked out just great before the uppgrade to winxp pro?
i use the same nocd cracks as before and the same patches,even tried uninstalling the games several times but it still dont work,all i get it error with exe file,and something about may be a hardware conflict

what drives me mad is that it worked out before,is there anyone who has any idea hat is goin on,thanks so much for you time
