Subliminal Talk

Hi there

I just bought PSE2 and noticed that there were 4 type of files in the download page File 1,2,3 and 4. I downloaded 1 of file 1 successfully and my system crashed downloading file 2, effectively wasting 1 download of file 2.

My question is, are these duplicate files of are they different? i'm loath to keep trying incase I'm wasting all my files.

Thanks in advance

PSE Version 2 (the whole set) consists of Volume 1, 2, 3 and 4 of the set. Each one is different, and each one is useful in different situations.
