Mac nerds using SL I need serious help!!!

[Ebony]

I mean that in the most loveable way (mac nerds )
I need you to run me through an archive and install on damn Snow Leopard.
I get to step 3 of this tutorial and it's coming up with no such file or directory

Please please please! I don't want to lose everything again.
Oh and I am using online back up software (backblaze) but after 3 months or so of the initial backup I'm not completely sure it was fully completed.

HELP!
