While exploring Runtime Revolution I was unable to view the tutorial videos. I had the audio content but a blank green screen replaced the video content. It turns out the problem is solved by disabling the Perian plugin for Quicktime.
I also was unable to do the WordPress automatic update thingy. This one was solved by disabling the WordPress Automatic Upgrade plugin which was conflicting with the automatic updating process :-/
I just mention these in case you are looking for a solution to similar problems.
