I've installed the last version of Microsoft Live Messenger. The problem I have is that it signs in to the server just if I start a Socks proxy. Otherwise, it can not signs me in, and tell me there is some errors regarding to Key ports. When I go to troubleshooting, the HTTP test is successful. But TCP test returns fail status when I did not run my Socks Proxy.
What's the problem ? I always get error "80072eff".

Tell us about your network connection and why you have a proxy – Paul Mar 24 '12 at 13:42
I use Proxifier to access some website that are filtered for me. Everything is very normal. A wireless network with an ADSL internet connection – Mohammad Bagher Saberi Mar 24 '12 at 14:36
Couldn't it just be that this is also filtered? – Paul Mar 25 '12 at 5:26
No it is not Paul – Mohammad Bagher Saberi Mar 25 '12 at 8:58
So you have a very normal ADSL connection, except some sites are filtered, yet you are certain this one is not, yet it doesn't work unless you bypass the filter? I suggest you contact your ISP. – Paul Mar 25 '12 at 12:23
