Can't launch the game with Mod Loader installed

[secondtry]

When I install the Mod Loader and launch the game I get this error
./scripts/mod_loader/modui/popup_gamepad-warning.lua:27: attempt to call global 'IsGamepad' (a nil value)
I didn't find anything about this error on this forum.

That error indicates you are using an older version of the game.
