Public Hack help

Well, yesterday I was playing CF with the public hack, then I quit the game. The next time I play it will be around 3 hours later, except when i try to launch skype, it doesnt work. I checked my folder and it seems that skype has disappeared. So I try dowloading the Public hack again, over and over at least 5 times, each time disabling my Firewall and Virus Protection, but after downloading it, everytime I try to extract it, only the .dll and settings will extract. The skype.exe refuses to extract, and I've tried using an injector but obviously, it wont work. Help please!!!

well if its being stubborn
just get OMFGZ injector or Perx injector
it's a simple solution
