Basically what the Title says, but to be more specific:

I recently "upgraded" from Windows Vista to 7, at the request of someone else. The thing is, I downloaded TS directly from the site normally, but it just doesn't get a Connection to anything. No Public TS Server, no private Server, not even the Server-List itself (the last of those always giving me a "Connection to Weblist-Server failed" Error), all I get is a "Could not resolve Host-Name" Message.

Ironically, from pinging at certain Servers directly via Windows-cmd, I know that I DO get a Connection to itself, which makes it all weirder for me

If it's of any Help, here's atleast a Text Dump from me starting TS and trying to connect to the standard public Server:

Oh, and before I forget, I apologize if I re-opened any FAQuestion, I am just getting frustrated already that all the common Solutions on the Internet don't work for me
