I'm using the VPN on my Windows 7 PC and my Android phone/tablet. I've tried to get it working on multiple networks already so I know it isn't an issue with my computer or internet connection. About two weeks ago the service was working great with the exception that PPTP is blocked on a lot of public networks (can't help that). Now when I connect it successfully connects to the VPN but when I try browsing the Internet it just hangs at "sending request" then finally times out. Programs like Skype don't work either. So I'm guessing something like the server-side DNS isn't working or my account doesn't have access outside of the VPN network somehow.
