Earle,
To open the Outlook application, use the shortcut to the Outlook application that is in your Start menu - you have used it before or you could never have had the Outlook application running. Then, as explained in para 1.8, wait for it to complain that it cannot find its pst file[s]. In the dialog that opens, browse to C:\Users\Earle\My Documents\PIM, select Outlook.pst and click onOpen. Outlook will now open the same file as it was using before and will go on doing so every time it opens from now on.
It is the Outlook application that then opens the pst file not you. pst files are not like normal files, you cannot just double-click on them to open them using their associated application as you can with doc or xls files.
