Okay. Let's try a couple of more things.
First, let's check to see that the movies are installing on your computer. Can you browse to:
C:\Program Files\Corel\Corel Painter Essentials 4\Resources\videos
and confirm that the FLV files are there?
If they are they, can you open Internet Explorer, and browse to this location on your computer:
C:\Program Files\Corel\Corel Painter Essentials 4\Resources\HTML\Videos
From there, can you drag and drop the "VideoPlayer.swf" file onto your IE Window? Please let me know if that works for you......
Thanks
Jennifer
