If that doesn't work, it could be caused by your anti-virus, if you have one installed. In that case make sure that your anti-virus and firewall are not blocking Gunz.exe and Launcher.exe inside of the FGunZ folder. (Default location at C:\Program Files (x86)\Freestyle GunZ) Add the entire folder and/or these individual files to the exception list of your anti-virus and firewall.
