said yes to the first question and no the the other 2 questions being you want to remove the addon manager etc.
When you replied YES to the question "Do you want to remove the Addon Manager" and "Do you want to remove the Couatl scripting engine?", the Uninstaller also told you that EVERY other addon requiring them wouldn't work anymore.
Installed the orginal and went to the airport and found all the ground texture were black
You can't use the 1.0 version anymore, unless you install it without the network connected. There's no reason why you would use the original version, since the 1.1 can be configured to be exactly like the previous one.
Went to another airport and all is ok except now i dont have gsx any more
That's why the uninstaller, when you replied YES to the question "Do you want to remove the Addon Manager" and "Do you want to remove the Couatl scripting engine?", also told you that EVERY other addon requiring them wouldn't work anymore.
I uninstalled cyvr and left cyvr fsx there and the texture were normal again but no gsx at all so doing the un install and re install has corrupt fsx some how
It obviously hasn't. It's you that, by YES to the question "Do you want to remove the Addon Manager" and "Do you want to remove the Couatl scripting engine?", have disabled GSX, which is why the Uninstaller warns you about it.
I just noticed now after the un install there are left over folders of cyvr do i need to remove these manually afte r the un install?
If you want GSX back, you should simply do the most logical thing, which is obviously *reinstalling* GSX, which will of course restore the Addon Manager and Couatl, you asked the CYVR uninstaller to be removed.
