Return of Reckoning

After downloading GTA 5 and much teeth gnashing I figured out I need a 64-bit OS to play it. I got the disc right here and a clean install is the solution, but that involves backing up files and such; but fudge that I want to play GTA 5 like right now and wax fools. Also I don't have the hard drive space to back up everything so of course I just do the install.

Now I don't have any of my RoR toons at login. I moved warhammer to new program files naively thinking that would work. Is there a way to get my toons back? I'm obviously computer illiterate tell me something good. I do see all my toons under warhammer/user/settings/martyrs square. Feel free for to flame frenetically.

Just install Windows 64 bit into another directory (e.g. Win instead of Windows) than the 32 bit version, so you could have both installed. There is no need to format the whole drive imo.
