[killer1093]

Hello guys,
How do i can null a script?
I bought a script but due to some issues, they block license, and i get error

Critical error: License is not valid.

How do i found this security and remove it from script?

Thanks in Advance:

This is a very complex question which differs from script to script. No all licenses work the same.
