Flash works on some websites but not others

[TheShums]

I have been struggling with some Flash player issues for a while. Most of these
were, I believe, due to a spyware infection that I have since resolved. I have
tried to uninstall and reinstall the player plugin several times. I have gotten
to the point where the Flash player plugin works for nearly every website I can
find, in Firefox and in IE7. The only thing that does not work is when I go to
ESPN.com while using my university wireless network connection -- certain
Flash-related aspects of this page show error messages or do not show at all.
After having visited this site, even when I use my laptop computer on a
different wireless network connection, this site is always corrupted in this
fashion. When I uninstall the Flash player plugin and reinstall it, these
aspects of ESPN's website function properly, but only when I am not using my
university connection.

All other websites seem to be fine, but ESPN is a site I visit a lot and I'm
at a loss as to what to do. I have never had a problem installing the player,
and I use WIndows XP Home so I have not used the SubinACL program to fix my
Windows system registry. I've read and tried most of the other solutions in
this forum and they do not seem to solve my specific problem. Any help anyone
could give would be appreciated.

Is the following key accessible in your system registry?

HKEY_CLASSES_ROOT\ShockwaveFlash.ShockwaveFlash.9

It seems to be accessible, yes. It's listed as
HKEY_CLASSES_ROOT\ShockwaveFlash.ShockwaveFlash.9\ CLSID. I can give you the
data string if you like. I've really never edited my system registry so I'm not
sure what I'm doing.
