The white background with a gray circle and exclamation point are typically a result of lack of available system resources to play a flash file. The grey exclamation point was implemented as a warning when flash shuts itself down to conserve browser resources.
Please try the troubleshooting tips below:
- Close other applications running in the background
- Reload your browser’s page
- Enable/Disable Hardware Acceleration
- Clear your browser cache
- Restart your computer
