If you are playing the game via steam, your game library will updated silently/in the background, this setting is set as default on steam client.
Empyrion Galactic Survival might have updated without you noticing it, and then you tried using the 1.4.3 trainer on the 1.5.0/1.5.2 version.
In my previous comment further up, i also had problems with the 1.4.3 trainer for the right version of the game, but it turned out steam client had an update and needed to be restarted, and after that everything worked. Maybe the steam client, game version and trainer version all need to be synced in order to work.
