Mini-How-To. Operation not supported on socket error.

[brute11k]

I'm using OpenVPN 2.1.3 for Windows 7 (both client and server-side are x64).
This is guide I'm using: http://openvpn.net/index.php/open-sourc ... howto.html

I'm trying to get connection over some LAN (intranet) (basically its two computers within one ISP, they can ping each other, but they are not in the same subnet) connection. Client IP is 10.133.71.31 and server is 10.133.66.79.

This is my config files: http://pastebin.com/ad1hUj91
This is client output: http://pastebin.com/XdFySMZ6
This is server output: http://pastebin.com/JB2jMT2W
We have disabled our antivirus software and windows firewall. We can't ping each other (pinging 10.8.0.1 from server and 10.8.0.2 from client works though).

Why client keeps getting this "write UDPv4: Operation not supported on socket (WSAEOPNOTSUPP) (code=10045)" ? How should I configure it properly?
Thanks for you time.
