Hacks help! key problem

So i injected and tested some hacks on mw3 and i had a little problem, the key i need to open the hack and such (Insert,Delete,arrow key to select the hack) are not quite working! i need to press them like 20 times so they will work but its only in the game, i mean i need to hold the arrow key on the keyboard so it will move, last time i tried to hack it was perfect no problems, but now this?! help plz

Get a new keyboard, don't know what you're talking about actually...

i can easily press the delete and insert and the arrow keys, the problem is the hack itself doesnt detect it!
