Newbie help w Mech Commanders2

[Nas50gt]

I guess I need a little or maybe a lot of help, I'm trying to backup mech 2 and i think i've replaced the EXE file but when they say "Burn the contents of the tempdir" i get lost because I'm not really sure which program to use to do this? nero, cdrWin, clonecd? most say copy disk, not just copy a file dir from my hard drive. I guess i'm just confused and maybe lost ?
any help would be great
