I tried to connect to Games For Windows-LIVE, but it gave me two problems. They go along the lines of this: that I it could not connect to the internet and than I couldn't sign in. After looking around for quite some time I found the solution. The official site says that I need to open the following TPC Ports: * TCP port 80 * TCP port 443 So my question is, how can I open these up? Thank you to anyone who can help me out.
