Same thing here (but the site opens), so it's a DNS problem.
Try using 8.8.8.8 (google's DNS) as your DNS server in Network Settings.
Or even better, before changing your settings you can test it first to see if it works:
C:\Users\Rolf>nslookup xnxx.com 8.8.8.8
Server: google-public-dns-a.google.com
Address: 8.8.8.8
Non-authoritative answer:
Name: xnxx.com
Addresses: 141.0.174.41
141.0.174.34
141.0.174.35
141.0.174.36
141.0.174.37
141.0.174.38
141.0.174.39
141.0.174.40
C:\Users\Rolf>
If you don't get a list of IPs as result as above, but get a timeout or something else instead (make sure you try at least twice), then Ogero is not allowing you to use other DNS servers and forcing you to use theirs, in which case you're slightly screwed (but not hopeless).
