Lo-Fi Games

I modded some weapons and added some things that I don't think I should have added and know I need to basically remove the item catalog and have it redownloaded.

is there a way to do this or is the game toast and I need to just reinstall the entire thing from scratch?

please help me fix my mistake it would be helpful to not redownload all 11+ gigs of this game
