Windows 7: Generals Zero Hour Networking Issues

Hello everyone!

I am glad to finally join this forum! I have looked here and found many answers to my questions post Windows 7 upgrade

I am having some issues regarding Generals: Zero Hour. I have done some searching within the forum re: compatibility issues. I am able to start the game and play single player just fine, but the Online play I am having some issues with

When going to Quickmatch, I am able to see my opponent on the initial matchup screen, but it always errors out. When in Custom Match, I am able to chat with other players, but when joining a game, it always says Host has left the game and I am booted out of the game.

Does anyone have any thoughts? I have it set for Windows XP compatibility mode, run as administrator, checked IP settings, etc. Any ideas would be greatly appreciated!

Thanks
