I have been playing fsx for years. Then I switch it on one day, it doesn't work. Saying FSX could not be read. So I deleted the .cfg file like I have had to do on 2 previous occasions which fixed the problem. But then it would'nt work, with the same error message.I then decided to uninstall. So I uninstalled and deleted all the necessary files (i.e. temp etc.) and tried to re-install. Now it won't let me re-install on my main machine giving me error 1305 saying 'verify file exists', no real solution on the internet helped so I decided to have a go on my brothers computer. FSX install perfectly. I activated it as soon as I could. But then the problems started. I installed my addons inc. Cap Sim 767,757 c130 but none of them have any CDU or any of the switches work. I check the .GAU files and they are all there its just they dont work. I have screenshots. As you can see they are grey and nothing is there. Help is very much supported.I HAVE RE-INSTALLED 5 TIMES SO THAT ISN'T AN ANSWER!!!!!!This is VC view the CDU and none of the switches work!!!This is with the apparent CDU up.
