[07:42:20.947] [Main Thread/FATAL] [tML]: /home/ubuntu/Games/Terraria/Terraria.exe is not the unmodified Terraria 1.4.4.9 executable.

This release of tModLoader expects to be installed alongside Terraria 1.4.4.9. If Terraria recently updated, you may have to downgrade to this earlier release in GOG Galaxy.

If you patched the .exe, you can create a copy of the original exe and name it "Terraria_v1.4.4.9.exe"
