These events are unrelated. You haven't indicated what browser you're using, but make sure, if you use Flash, that you have downloaded the most recent version from Adobe. Also, if you are using Safari 7, it doesn't load Flash video automatically, in most cases. If you use Chrome or FireFox or Opera, make sure your browser is up-to-date.
Also, you haven't mentioned whether you use gmail in your browser, or you use it in your email client (e.g. Apple Mail). In any case, it should have no bearing on whether you can use Flash.
You might try refreshing your browser, closing all open tabs, and quitting and restarting your browser. Make sure you have no add-ons, plug-ins, or extensions that might conflict. If there's a question, turn all of them off, or uninstall all of them. If you need further help, reach me via phone at
