If you downloaded the trainer with the MAX INVENTORY option, just delete that trainer and re-download the new trainer. there were too many problems with that option and we don't want any people having issues with this AAA game. You can use the praxis points and etc. to increase your inventory space later in the game.
Also, this was created with the STEAM legit version of the game, so please note your VERSION NUMBER and that it is STEAM when using the trainer.
As usual, it's always BEST PRACTICE to SAVE YOUR GAME before using any MODS or TRAINERS, especially if you have put hours and hours into the game.
