Please Help: " *.class" Files All Changed To One Program!

[wildwoods]

In XP Prefessional, all of my " *.CLASS" files have
converted to my "Photo Deluxe" program. All " *.CLASS"
files now have the "Photo Deluxe" program icon. In "Help"
one is instructed to manually select from a list of
programs to revert the changed files. However, the only "
*.CLASS" extension I can find in the list of programs is
now also a "Photo Deluxe" icon! I wouldn't know how to
revert each file seperately, and there must be over 200 "
*.CLASS" files in XP Professional.
Is there any way to revert these " *.CLASS" files back to
the way they should be (the way they originally were)?
I can't use "Go Back", as I don't know when these files
became corrupted. Thanks in advance for any help
extended.

Control Panel> Folder Options> File Types You should be
able to find it and use "advanced" and change the Icon

Thank you, "Willit", I have gotten that far.
However, once in there, it won't revert itself as some
files do. I have to make a choice there, but since I
cannot find the "CLASS" icon to apply, I don't know which
goes with "CLASS".
I'm all out of ideas!
