Please Help, Flash Player for Mac

I am running Mac OS X 10.7.5.  Last night Facebook told me I MUST update to the newest version of Flash Player in order to upload multiple pics.  I kept getting plug-in failure messages and then the message saying I need to update my version of Flash.

Problem is I have updated my version of Flash and the plug in still doesn't work.  Please help, my business relies on my being able to upload multiple photos daily to social media.  What is going on?  I have read the forums, the work arounds posted on 4/16.  Uninstalled, re-installed, etc.  I am still getting flash plug in failures even on Adobe's site.  What do I do?
