This error is typically seen in OSX 10.9 and 10.10
If you encounter this issue, please Exit Jing completely by hovering over the Jing Sun and then clicking on More >> Exit Jing
After that is done, open Safari (this must be done in Safari) and navigate to the following page: https://get2.adobe.com/flashplayer/
Using Safari please update flash player to the latest version and then restart the computer. Jing should be functioning without the above error afterward.
