Fatal error messege

[captainklm 1]

hello,my previous problem has been solved, I reinstalled fsx. I think I downloaded to much crap onto it. Anyway now this is my problem, the NGX flies perfectly but nothing in the cockpit works. No PDF no FMC and none of the buttons work. Then after a little while I come up with a fatal error messege and it crashes. I really wish I hadnt wasted my money so please do help

Have you tried before and after applying hotfix?

yes, no difference

can my cfg file have something to do with this?

now its working like a beauty, but the only problem is that there is no text on the flight displays, no speed indications no altitudes, only the secondary systems work
