I posted this first because I wanted to get the "System is probably too weak answer out of the way

The problem first started when I installed patch 6.4, worked fine on 6.3

I am currently playing as The Kingdom Of England with the graphics set to the highest possible. When the fatal error pop up appears (It has now several times) It says to lower graphics. I'm willing to lower the graphics, but I want to try and fix the problem without doing so.
