Reply to Recovering Ableton Sets

My friend spilt tea on his computer. But we got the whole hardrive backed up onto an external. When i go into macintosh HD, then take out the live set, it says samples offline, and it wont play. One song we have taken and frozen then flatten all the tracks and this one plays 100%. I bought massive while he torrented it so I went back to the torrented one to make sure its compatible. We never collected all and saved. When I open the folder which i placed into my macintosh HD MUSIC folder, it contains a mini folder with Ableton Project Info, Then the project itself, Then a mini folder with samples. I took all of this onto my computer.

Advise please.
