Hello! I just made this account so that I could have my question answered. Why can't I connect to steam so that I can begin my Left 4 Dead installation?!?!!? Every time I try and install Left 4 Dead, the same message appears: Cannot onnect to steam network. This could be a problem with steam or with your internet connection. I can connect to the steam website I even have 2 accounts! I've tried everything from plugging my modem directly into my computer, to getting rid of my previous anti-virus program Mcafee and getting Norton to completly shutting down ALL my firewalls! Can anybody help me! I am insanely frustrated and I just want to play Left 4 Dead! I didn't even want Steam in the first place!

You are likely gonna have to go through the Steam troubleshooting guide first.

If no luck there, then post FULL specs for your rig.
