"It seems your pc is not reachable etc etc."
Is it possible to get a detailed explanation how to fix this ages old problem? I'm not terribly computer savvy and obviously this requires something more complicated.
I'm on windows 7 and I have went to control panel and "windows firewall" and on the traffic list there are 2 tennis elbow slots that I have both checked(also have tried turning my firewall off). Still unable to host games. This is where my skill ends so I ask for some help how to proceed.
I don't have any problems that I know of with my firewall or connection except with tennis elbow. Also in the past I have been able to randomly host games without changing a thing in my settings but the ability has come and gone seemingly without reason(though I could swear it changed due to updates on the game). It's been a while since I was able to host though.
