help! screwed by adobe flash upgarde

win98 ns7.2
I did my usual weekly check of macromedia version, was informed of update to 9,0,28,0 (from 9,0,16,0), downloaded it to my separate "download" folder.
Since it had the same name as the previous install, I told it to 'overwrite' (big mistake). Doubleclickto install, no problem. Now Netscape won't work.

Netscp
"...has performed illegal operation..."
"...invalid page fault in module NPSWF32.DLL at 0167:300a8722." and a bunch of Register info and Stack dump info.

How can I get 9,0,16,0 back???? I didn't see it on the Adobe site.

Please help ASAP.
Thanks

 

Sorry for the late thanks.
I did as you suggested but no change.
I found an archive of 9.16 and put it back on. It works ok, so I guess I'll just not risk anymore updates.
Thanks again.
