Problem with Battlefield series.

[DCfra]

Well, I downloaded a no CD patch a while back and installed it. I think it was for Battlefield Vietnam. Then ALL of my EA Battlefield games (1942, Vietnam, Battlefield 2, 2142) stopped working at full potential. When I run them, sure they seem to be running alright, but the video settings are always set to the lowest because I CANT change them for some reason, including the resolution settings, which are stuck at a max of 1260x1024 while I use a 1900x1200 screen. Also, when I do try to play online, everything is like I have a ping of 2000 and I usually get disconnected. Funny thing is, I have all of these games, like the real copies, but I tried installing the no CD so I could play with a friend...

I dont know what to do. I reinstalled all of them with no results. Has anyone ever had this problem before? what do I do?

I even reinstalled windows for this damn thing...

Help!
