Thanks for the suggestion. I renamed the avi folder. A couple of things happened as a result.
(1) The game loads immensely faster because there are no videos. Also, before renaming, when the videos loaded my monitor flickered between screens. This no longer occurs
(2) The game loads up perfectly, as it did before.
(3) The save games still won't work. If I keep the game paused before I click the begin scenarion button, I can scroll around and click on provinces and CoT's and everything, like before. However, as soon as I unpause the game, BOOM, I crash out of it.
(4) During the crash, my desktop reverts to 800x600 for a few seconds before restoring to my normal 1024x768 resolution. I had thought the new video card drivers and DirectX would have solved this, but apparently not.
I hope this enough information for you to help me fix the problem. Because its a 400 year long game, not being able to load saves makes the game unplayable, which is unfortunate, since this seems to be the best game I've ever played.
Thanks for your help!!
