You tell me to backup a working copy of Logos 4 - how do I do it?
Copy C:\Users\<UserName>\AppData\Local\Logos4\ [Vista/Win7] OR C:\Documents and Settings\<UserName>\Local Settings\Application Data\Logos4 [XP] to an external HD or some other place.
Thanks, Kevin, I've done it with your help! Now I don't have to panic if my computer crashes!
