help with thunderbird?

Okay, the madness is over.
I've dealt with the PC problem by just installing
a second operation system on the second harddisc,
so I at least have access my files.
Now I wanted to transfer my thunderbird-profile,
but I just can't find it?
Mozbackup doesn't find anything either...
WHERE IS MY MAIL??? If you had to deal with
something like this, I seriously would appreciate
advice. :(

This sucks so much...

Edit: Problem solved. XP was just hiding essential folders from me, even from the search, oh lol wtf.
