Norton Runs Clean - Lost Email Folders

I have a Compaq laptop on XP that is up to date. Norton runs clean. I believe my modem is going bad because whenever I�m on the internet and minimize IE the computer locks up. In about five minutes it starts running and all the things I clicked on while it was locked up appear, as if they were all running in the background. The pc works fine if I�m not using the modem. I�m on vacation and have other modems at home. Several times I held the power button down when it was hung up. One of those times I lost my profile so that when it starts up it can�t find local settings and it has to build a temp profile. I built another profile but all of my old Outlook folders are missing. I�ve done multiple searches for *.pst but can�t find them, even looking in hidden files. I�ve found an old pst file that I made as a backup last year but when I try to load it into my new profile/ user it says I don�t have permission to access these files. The new user I built is set as administrator. I tried moving a copy from the cd to my user but then it asked for a password which I never set. Here are my questions,

1)Is there any way to find the folders in my old Outlook?
2)Is there a way to change the permission on the old pst file on my backup cd? I tried finding it in the registry after I moved it to my user but was unable to?
3)Scanpst.exe needs a pst file to work on which I can�t find.
4)I�ve reloaded the driver for the modem but that didn�t help. Any thoughts?
5)When you archive the mail where is it kept? I did this last week.
