She is working beautifully!!! I had a combination of factors that I think was causing my issues.... The plane would take extremely long to load into the free flight menu, then even longer once you got into the actual flight, I had a suspicion that the sim was struggling to find and acces the NGX dlls, as when I recreated the fsx.cfg, it would take extremely long to ask to register and approve the dlls, so that was the first of my problems. So either my FSX install had gone for a ball of .... or my Windows registry was corrupted, I don't know, but find it strange that these porblems only popped up after the NGX install, anyway my hard drive that had FSX installed on then decided that it had had enough, and started giving me I/O errors So I decided to buy 2 new Hard drives as both of the old ones were the same and I did not want to suffer the same fate with my OS drive... So I installed Win7, installed FSX and the NGX on the new drives, and now she works like a charm! I am sooo happy! Cannot wait to get home this afternoon and FLY!!!

That's a great story, always a very nice feeling when you're able to solve a problem like this! Enjoy your flying when you get home today :(
