Guitar help

I have a Jackson DXMG guitar with a floyd rose tuning system. I was changing my strings when i tried to replace G. The clamp at the nut for the D and G strings are jammed. Even when i removed the entire screw, the clamp is still firmly jammed closed. I had to forcefuly pull the string through the clamp(which i probably shouldnt have done). Is there any way i can loosen the clamp? I tried prying it off, but i couldn’t get an implement sharp enough to fit and it just scratched my hardware.

Never mind, i fixed it with a screwdriver.
