Just to be sure - you used the Adobe uninstaller to completely remove old remnants of Flash from your computer before reinstalling the latest version?
The next thing I can suggest is to update Java. Here's the link to the downloads page: http://www.java.com/en/download/windows_ie.jsp?locale=en&host=www.java.com:80
Let me know if you run into any obstacles.
I get the above error and have followed th einstruction sissued previously about uninstalling Flash and then reinstalling it.
I'm running Win 2k and IE 6.0.2800.1106
Does anyone have any ideas?
