I updated GSX through the FSDT installer the other day and before that Couatl started perfectly and was running well in MSFS. Once updated it wont allow me to open Couatl, I have tried opening the programme as "Run as administrator". However this didn't work so i uninstall GSX/FSDT products completely. Downloaded the offline addon manager and it still will not open. Can anybody help please?
I am trying to open it from start page in top left of screenshot
