Sorry that i posted this again but i dont know where my old post is so i dont know if its answered or not.
I played u4 a bit and had a fun time with it then i heard about xu4 and i installed that but when i start xu4 i dont have load game does anyone know how i resolve that?

it may depend on which OS you're running, on my XP machine xu4 stores it's savefiles in "C:\Documents and Settings\<insert user name here>\Application Data\xu4\"

in Windows 7, IIRC, it would be "c:\users\<insert user name here>\appdata\xu4"

Vista I'm not too sure on, but prolly similar or the same as Win7

all you have to do is copy your old <savegamename>.sav file to xu4's appdata folder
