Help! Can’t find a much needed Outlook mail folder/file~!!!!!!!

I hope someone much smarter than me is up right now! My old pc died (running xp and office 2k). Replaced with Vista and trial of office 07. I have info I desparately need in my old hard drive which is attached to the new tower via a maddog device. i can get to both legacy partioned drives, but when I try to open or find a pst file in the old \camilla\app data\microsoft\outlook folder the I don’t see a pst file there. Am I missing something? I really need some info in there for daughter’s HS graduation this Sunday!!!
Thanks – in advance – to anyone who can help me.
