Fluxus Key Fix

Fluxus is very great It has cool features and can execute alot of things. But my only problem with it is the key system. Everytime I use Fluxus for atleast 5 times it keeps making me have to put in another key again and again. It's getting really annoying to me now. Everytime i'm about to use the perfect script for a game I have to get another key. Can you guys please make it stop? For example, in Assassin when I was trying to use my exploit (Fluxus) I had to get another key once i had did that 10 minutes later had to put another key
