can't connect to connection

[blaming]

(I use Windows 7). I have successfully connected to my desired OpenVPN server, and my openvpn client has created the connection. Unfortunately, there is no way to actually connect to this connection in my "Network and Sharing Center":


The connection is listed as Unidentified Network, and Windows claims that it is "public". Upon looking at the "status" (log?) I get this:

Mon Jan 09 20:44:03 2012 Notified TAP-Win32 driver to set a DHCP IP/netmask of 172.27.0.7/255.255.252.0 on interface {9DB2A2EA-9110-4241-A95E-64F3FD68F1CB} [DHCP-serv: 172.27.0.0, lease-time: 31536000]

I initially interpreted the "the requested operation requires elevation" as meaning that I need to run openvpn as administrator, yet even when I do this it still doesn't work (same thing happens as the screenshot above), and I get these messages instead:

What can I do to fix this?

Disable firewall on TUN interface and run OpenVPN with elevated privileges.
