I just downloaded the latest version of Windows XP, the 64-bit one. And installed it in Parallels on my late 2012 iMac. Age of Empires II runs like a charm. However, when I try to connect to somebody running the same version of AOE it won't show that user's game. I know the fault is with me because others have been able to connect. I disabled the firewall in Windows XP and the iMac is connected directly to the Internet so there are no hardware intermediaries that can mess things up. But of course the big elephant here is OS X and Parallels, could it mess something up? Anyone has any ideas what I could do to solve this?
