Having Lan issues with Zero Hour

[Battlemaster24]

Well I have been playing since 2003 and well the last time I played it on Lan was in 2006 when I had just gotten out of dial up and my router wouldnt let me play it on Lan or online at all recently got a new router and I still cant get Lan to work no matter what. What is wrong?

Are you trying to play via direct connection to another computer???

Also, what are the OS's of both the computers you are trying to play via lan on?

I am also having the same problem--using vanilla ZH and the Shockwave mod--when I try to get into a LAN match with my sister, we've trying routing wireless through our house router, VPNs, and through Hamachi, and zip. We can't see each other no matter who's hosting. We're both running Win7 on different laptops with specs -way- above the min to play games like this...any and all help would be -vastly- appreciated.

Do you have two copies installed? As it is not supposed to work if you installed the same copy and thus have the same serial number.
