Why doesn't the RealTimes (or RealPlayer) library display the thumbnail images for the videos I downloaded?

To resolve this issue, clear your thumbnail cache:

1. Click the Windows Start button and type "disk cleanup" in the search field. Press enter.

2. Check the box next to Thumbnails and click/tap on OK.

3. Click/tap on Delete Files.

4. Disk Cleanup will now clear the thumbnail cache and close.

5. Restart your computer. The thumbnails should now appear in your RealPlayer Library.
