Norton WiFi Privacy - Not Connecting on any devices to VPN

I have paid VPN subscription for 5 devices. All have been working fine and connecting overseas for the last month. Up until the last few days I cannot get any of them to connect. Please help! Thank you!

I gather you are speaking about Norton Wifi Privacy???  What version are you using? The current version is 1.2.162.

Have you restarted your computers? If you use Windows 8/8.1 or 10, there can be an issue with the Fast Start feature.. See more information here.
