Hi, When you refer to ADM are you speaking of the DLM(download manager)? If so don't use that. Instead go to this Troubleshooting Guide and make sure you have all of the IE Settings correct. Also check the Permissions section as you need to use the Administrator Account. Then after Uninstalling, use the Manual Installers. Don't forget to Reboot(restart) your computer after Uninstalling and also Installing.

Once you have made sure the Settings are correct, then you can SAVE the Uninstaller to your Desktop.
Download and SAVE the Manual Installers to your Desktop.
Make sure you disable any applications that use Flash (see system tray-area near the clock) such as MSN messenger or any others.
CLOSE all browsers, then Run the Uninstaller, Reboot, and then Reboot again.
Then Run the IE Installer, then the FF Installer(if you use it, if not don't even put it on your Desktop) Then Reboot.

If you have any questions, just post.
