yes FSDT universal shows that GSX is installed and I have already tried to delete the virtuali folder, + Addon Manager to reinstall everything. ( New file Couatl )
Your log now shows the fsdreamteam-gsx-world-of-jetways seems not to exists in your community folder, or can't be accessed for some reason, but it seems you removed the trial package.
And your Couatl is a more recent version, but is still outdated, the version which is online now and it's included in the latest Offline installer is 4.8.0.4849, so you are still some versions behind.
After reinstalling, try just the offline installer, which you must download anew.
