Mp game problems

[CommandoEmu]

After getting a new computer, I found I was no longer able to join or see my friends games in the MP lobby. So we tried to do direct Ip games and that did not work either. The only thing that has changed from my old computer and the new one is the old one was Vista and the new one is Windows 7.

I have tried manually allowing ports to be open, and has not worked yet. So I am at a loss as to what could be wrong or how to fix it.

Any help would be welcome and ty in advance.
