Thank you Jim - Both for your advice and your time! I shall look into this further.Have a good Christmas and a Happy New Year.Regards,Matthew.

Hello and thank you for replying.I tried the .cfg solution but it did not solve the issue. However, I took off 'World of AI' and all of my add ons and left FSX on. It started working again and I re-installed my add ons. All is working fine but I have not put 'World of AI' on again.Do you think it was because I tried to put too many airlines on 'World of AI' all at once?Are there any tips on putting 'World of AI' on Windows 7 64bit?

I have had no problems with FSX until today when I tried to install a whole load of AI airctaft and the AITC Programme.I have uninstalled the lot but still get the dreaded 'Fatal Error' message when I start FSX.I have deleted the traffic.bgl files from WOAI and I think I have removed all WOAI files.I have also ran it as Windows XP and Administrator. I do not like the look of downloading the .dll file mentioned in other forums as that causes issues in other Windows programmes.I do not think I can face uninstalling everything and starting again!Does anyone have any ideas?Windows 7 - 64 Bit // AMD6990 4gb Graphics // 16GB Ram // i7 2600 - OC 4.8ghz
