That's one option that's been known to work at times. If it doesn't, doing a Global flash purge may also help:
If you're on Windows, go into the start menu and enter*into the search bar "%appdata%\adobe" --> then delete the Flash player folder.
Next, enter into the search bar "%appdata%\macromedia" --> once more, delete*the Flash player folder.
If you're on a Mac, go into your System Preferences --> select "Flash Player" --> select the Advanced tab --> Delete all.
