Internet doesn't work unless vpn is on

I mistakenly downloaded hotspotshield, the free VPN. I uninstalled it and noticed that nothing would load, almost as if my wifi wasn't connected. I reinstalled it and found out that unless it's on, nothing except firefox works. I can only visit the steam store when it is on, chrome only works when it is on but firefox works fine, league of legends only lets me log in when it is on but after that I can do whatever. How can I fix this? I want it off my computer but I want to be able to access the internet.
