Sometimes there is a problem with anti-virus or firewall, try to switch it off or do an exception in their rules, also you can try "Run as Administrator" maybe it will help.
I don't know what anti virus you use so i cant help with that, but i can help with firewall, just go to start menu, type in in search , you should get result "windows firewall" click on it...their you can see "Turn windows firewall on or off" click it...and just turn off firewall. if you don't want to turn it off you can do an exception in firewall. Just go into windows firewall and go to "Allow program or feature through windows firewall" , their scroll all the way down and push button "Allow another program" , now just browse to the hack, select it and push add. Allow access to your network and click OK. And to run as administrator just, right mouse click on the hack and chose "run as administrator" . I hope it will help you. I have Win7 but i don't have any problems with hack.
