^ referring to me. For what it's worth, I also cannot host games. Epic freeze when I hit the button, have to ctrl+alt+del to abort the program. Skirmish/Pantheon just keeps looking for an opponent and says that I'm the only player searching.
I'll update after the reinstall. Here's hopin.
ED: Reinstall fixed the problem! This was after updating router firmware, opening ports, disabling firewalls, even trying a different modem, all to no avail. A note for anyone with this same issue: Do not simply Verify Installation. It told me that the installation was correct, but it apparently was not. Nothing was changed before or after the uninstall/reinstall, it just decided to give me the goods.
Best of luck.
