I would make the changes I mentioned, in the spreadsheet file, save the file, and then start the game loading and a screen would appear that their was no direct X surface. if I did not make the changes it would load and play and I could play for hours even days before winning or loosing. As for the number of spies mentioned this would be how many I could have on file to be trained. I choose 39 just for grins and it loaded, in the past. I tried more once but the game did not like it. As for the test I attempt now, I only increase the number to 5 from the normal of only 4, and the dreaded message, no direct X surface appears. I have not attempted to go back in and change it back to 4 to see if will load or not, just never thought of it. I was usually to upset to think at that point.
I must admit, I never tried ;)
But If you haven´t had a problem before, I must admit, I don´t know why ;)
But JUST to be sure, you make the changes to the save file, correct? ;)
I don´t see how it would correlate with graphic.....
And you are sure there wasn´t an update of the game (not that I know of ;) )
Aaaand one thing which jumps too my head: You are still the host?
AFAIR the host stores the reference....
