|||Hey, Im wondering if you got your problem fixed because I am having the same problem|||

I have the same problem since yesterday.

|||Try repairing your TC/IP stack.|||

I get the same problem/error....cannot even play after loading this onto my computer and was very excited.....what a bummer.

How do we fix this please??? Detailed instructions would be appreciated.

|||Also Windows updates may enable windows firewall.|||

Anyone having this issue........I had same issue and repaired my TCP/IP Stack.....I had no idea how to do the repair.....I found this link that does it for you automatically.....I tried it and now I can get into game!

Select the link to "Fix it for me".......hope this helps someone....because I know I was really aggitated that I could not play.....good luck.

If you are using a Xbox then test your UPNP with the Internet Explorer Internet Gateway Device test. Make sure your Router/PC has UPNP enabled before running the test.
