When Ill start my CS2D it goes up to "U.S.G.N: Checking game version". Then it freezes and after a while comes timeout.
Still, on CS2D menu there is green text "logged in as chth"

I can make my own server, and other players can join, but I cant retrieve serverlist. It just gets stuck "Loading serverlist". Ive tried to keep it open for 30 minutes but no difference. I cant retrieve any servers, whether they are U.S.G.N or non-U.S.G.N -servers.
Ive tried getting IPs manually from USGN page, but I still cant connect any server through favorites

I dont have NAT or any hardware firewall. Only firewall is Windows Firewall, there is an exception for CS2D, and Ive tried with windows firewall off, still the same result.
My antivirus is Avast, Ive tried turning it off too but no difference.
I installed wireshark and looked for packets.
4 tavun UDP-puketteja portista 62057 USGN.de -osoitteeseen porttiin 36963 (josta palvelinlista haetaan), mutta Wireshark näyttää notta Header Checksum olisi väärin (0x0000) vaikka sen tulisi olla 0x964d.
I shouldnt have any hardware problem, my computer is pretty new etc. I havent blocked any ports from my modem, neither my ISP has afaik.
Downloading torrents, getting serverlists from Steam games, hosting webserver etc. works just fine
