Welcome back to the community. 
There are over 60 trainers for the Steam version of Conan Exiles here at WeMod.
You can see them all by clicking Mod Settings > Mods Version.
Older versions are unlikely to be compatible with newer game updates.
I played the game a few months ago and did not experience any problems with the WeMod trainer. But we’ll ask someone to check anyway.
In the meantime, make sure that:
- Your copy of the game is purchased from the Steam store.
- You are using the most recent trainer, by following the instructions given above.
- Your copy of the game is not cracked or pirated.
- You are playing solo, not attempting to play in multiplayer, co-op, or on any online servers.
Kindly direct and continue any future discussion on this trainer to the trainer’s official thread: Conan Exiles Cheats and Trainer for Steam
