Permissions help

So, i just joined mpgh cause i got bored of the game really. and i tried to download a hack, and an injector. but none of the injectors will work. I keep getting permissions error
some of the things I have read and looked up say to run as administrator:check
be an administrator:check
allow through firewall:can't because of permissions
OS:windows 7

any ideas?

Edit: read above

well run the injectors as administrator, as simple as that. right click on the injector and click on 'run as administrator'.
