We will need to do further research to determine the cause of this error. To help us investigate, please provide the following information:
Is this error happening only when playing a media file, if so what format (extension)? If not, is this happening when starting RealPlayer?
Have you updated RealPlayer since March 18? If not, please open RealPlayer, click the RealPlayer logo at the top left, select "Check for Update" and follow the prompts. Let us know if the error still persists after updating.
Please check if the RealPlayer system tray process is working correctly by following these steps:
a. Click on the hidden icons arrow in the lower right of your computer screen, near the clock (or press the windows icon and B on your keyboard)
b. Right-click on the RealPlayer icon.
c. Click "Go to RealTimes Web" -- the realtimes.real.com website should open in a new window if everything is working correctly. If this does not work, let us know.
