so what made you guys figure that particular url was safe to click on, anyway...(rdl)
I would create a test user account belonging to the aministrators group and see if that worked. my guess is the ActiveX control for flashplayer is blocked by your Internet Options Security settings or is corrupt or you had an old version before and now have mixed install. if you think your browser security AND user permissions are not causing this problem, i would manually uninstall then reinstall flash.
here is a snippet from macromedia support faq's about the required browser security settings.
Internet Explorer ActiveX settings
Although your browser security settings should be chosen by you or your system Administrator, the 'Medium: Default Level' will allow you to view Macromedia Flash content. For any Custom Level, ensure that both "Download Signed ActiveX controls" and "Run ActiveX controls and plug-ins" are not disabled. (Enable or Prompt will work).
To view your Security Level do the following:
Open Internet Explorer.
Choose Tools then Internet Options.
Select the Security tab.
Choose Internet.
Ensure that "Download Signed ActiveX controls" and "Run ActiveX controls and plug-ins" are not disabled
