Rommel takes the Suez

[zap]

I was attempting to play Dans scenario. But it seems I must be missing a file to be able to open the turn. What happens is I open the turn sent me When I choose the no replay button It begins to unload the turn but kicks me out and sends me back to desktop. 
I have a powerful processer, 32mb of ram. Gaming computer with a geforce grafics card. Both players got the download from the same source. So thats why i believe i might be missing some file that will allow the turn to open. I ccan open all other scenarios large and small. So it has to be something particular with this scenario needing a file i dont have in my game files.  I do have IOBits malware program running or is it a windows issue.

Any ideas??
