I do a lot of surveys, and since I got a new computer, I cannot connect to a lot of the sites. A lot of them are advertisements, but there is one major survey site that won't connect. It is OTX.
My old machine had no problem, but this one just won't do it. Same OS - XP Pro. The only thing I can think of is that I bought it refurbished, and it used to be used in a big company that had them networked. Maybe that has nothing to do with it if it was refurbished right. but I've done everything I know how to do to allow different sites to be OK.
You'll probably need more info, but if I knew what that was, I could fix it, so ask away, and I'll answer the best I can

Try and add the site to trusted sites

-tools, internet options, security tab and highlight trusted sites and hit the sites tab right below it

-now add the site you are trying to go to in there and click OK

-close out options and try to go to site

-see fi this helps
