Another morning wasted
I too wasted half a day sorting this problem out. This was not helped by the fact they partially blocked access to Teamviewer's network (just enough to stop the client, not enough to make this clear). If they had put an intercept page when going to Teramviewers website stating what they had done then I might have saved hours 'repairing' every possible fault with Teamviewer on my PC. Fortunately I managed to work-around the problem by getting Teamviewer to use a Proxy the other side of TalkTalk's network. I think I will have to leave TalkTalk as this behaviour is simply not acceptable from my ISP.
Biting the hand that feeds IT
