Your error log shows you are running an OUTDATED version of the Couatl.exe, since the current version is 3985, so you are several versions behind.
Normally, it's not possible to get an outdated version after running the updater so, the only possible explanation is that your antivirus might have blocked the download of the current version, so you are stuck with the previous one, but it let pass the other program files and, when files from a new version are used with an older version of the executable, it's very likely you'll have all sort of errors.
- Configure the antivirus to exclude the Addon Manager folder
- Run the FSDT Live Updater again, from its Desktop icon, when the sim is not running.
