Please note that we decided to remove one option (Max Inventory) to reduce the chances of crashes and corrupted saves. We might add it back if we can nail it down some more.
YES 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.
