No list content, computer help needed

If there is anyone familiar
with Win 98 SE and Shockwave
Flash, please contact me off
list. Friday, all my SWF files
are not opening. My Shockwave
is not working anymore. I
deleted the old program, and
downloaded a new one, and
after I ran the install, they
still won't work. Any ideas on
why they just stopped working
all of a sudden? I ran virus
scan, spybot, and adaware to
no avail. TIA
Brad
