EF & WF Problems with PBEM

[Boisforas]

Gentlemen, Boiusforas here with another problem I hope some one can help me with. Currently Iam PBEM with an opponent who lives in Germany & we keep having problems with turn number 3 in both EF & WF, to whit: on my turn 3 in both EF & WF,  after I down load the move & get to the "Do you want to see the battle replay," when I click on "no," the screen goes black & theres a white arrow I can move but no change. If I click "yes," I get to watch my opponents move but after his move is done, the screen goes black & I get a message saying, "WF(or EF)exe. has stopped working."  This only happens with this opponent as Im playing several other email games with over seas opponents & I have no trouble. Any suggestions?
