We are aware of this and our product team is trying to figure out the root cause of this issue. Once we have an update on the status of this issue, we will let you know.

Note: Ensure that you also delete the RealPlayer folders as mentioned in the above article.
I couldn't uninstall real player since it didn't appear in the list of programs. I did, however, reinstall the program, and that worked. I can now download videos once again. There is a hitch though. There is only audio, no video. The video is there - when the file is converted to a wmv, the video shows up, but there is no video when playing the file with real player.
