First I'd like you to grab these drivers
. If I remember correctly these will be from November of 2009 instead of September.
If the drivers alone do not stop the errors it would be good to run Eden in compatibility mode for Windows XP as well. To do this all you need to do is right click on the Eden Eternal shortcut, select properties, click the Compatibility tab, check the "Run this program in compatibility mode for:" box and then select Windows XP SP2 or SP3. Then click OK and try Eden again. This works on Vista and Windows 7 and usually benefits people with Intel graphics chipsets most.
Additionally, some people have luck with deleting the _Launcher.exe and then running the launcher.exe from the Eden folder. This replaces the _Launcher.exe that can sometimes become corrupt.
