Hi
I have just downloaded AoE II patch 2A but whenever I try to install it I get a message saying it's already installed. The computer has a new install of XP Home and AoE II on a newly formated harddrive. The file details say Version 0.14.22.0172. Any help appreciated
                                                Thanks
