Hi there, I am Cris and will be glad to assist you.
Can I offer you secure remote support so I can log in take a look at your issue and resolve it?
Can you tell me what browser you are using for facebook and farmville?
Internet Explorer, Firefox or Chrome?
OK, reset your chrome browser, click on the icon which looks like three small dots stacked top right of the window.
From the drop down click on Settings, in the Settings box Click on "Show Advanced Settings".
Scroll all the way to the bottom and click on "Reset". The browser will reset, then open it back up and try to re-download Shockwave Flash player.
Let me know how this solution works for you and if we have to further troubleshoot.
