Since upgrading to latest version of Teamviewer, it now can't find my internet connection. Browsing on the same machine works absolutely fine.

Running XP (yes, I know, it's old) with Service Pack 3 - but everything worked fine before the last update. Windows Firewall allows connections. Rolled back to version 8 but it says "not ready...please check your connection" after installing. Tried stopping/restarting the service. Has anyone got this working in Windows?

Also - AVG continuously reports an error, saying that the connection is offline. Everything is enabled (that I can see) in Windows Firewall. Am I missing something here?

Edit: someone suggested it might be something to with IPv6?
