commander keen

i am frustrated, My wife and i love MO2, think it is the best mod ever, she has a computer running winXP pro32, i have a computer running vista ultimate 32. and i used the wsock32.dll to gain play via ipx. each computer has exactly the same software, patches, and updates even the same maps. i even just reinstalled the games to be sure of this, but in MO2, i get a message when we try to network stating access denied, wrong version, go to westwood..... i did not use the online patches to upgrade red alert or yuri, i used the ones i downloaded, this was because the vista machine wouldn't run the yuri patch online. i have purple alert, it plays fine, and i installed the Command & Conquer Yuri's Revenge Skirmish Pack Final in both machines, they play fine.

ANY SUGGESTONS???
