Very similar problem to that described in RogerRampant s post. I want to use Topcashback site but when I try to click through to vendor I get the "unable to connect" message ( see attached jpeg ). I have set Spywareblaster to ignore cookies from Tradedoubler ( hope this is the same as clkuk.tradedoubler!!)& looked to see if I can find the hosts file roger refers to - I cannot.Checked to see if it is blocked by Spybot S&D. Just don't know where to look next to enable access to clkcuk.tradedoubler I guess there is safe & too safe!!!
