problem with OE and pstores.exe

[Special K]

For some reason, Outlook Express now takes forever to load. Task manager will show the program as not responding, but if I wait long enough it will eventually load. After reading this and looking at the pstore.log file, I think I have narrowed down the problem to be with the pstores file (and/or anything associated with it). The only problem is, I did what MS recommeded in that article, and then did 2 formats and clean installs of win98 SE, and yet the problem still won't go away. The problem was even present immediately after the clean install, before any windows updates or patches were installed. Anyone have any advice?
