You are still running several plugins that could interfere with the IXEG, they are encorporated in a lot of the Custom Scenery you have.

I am not saying that any of these are the culprit...but they very well could be. The only way to find out is to remove them and run the IXEG without them - then see which one is the conflicting one.
Also make sure your gfx drivers are up to date, of course.
Let me know how this goes, Jan
