I recently upgraded to mountain lion and now I cannot view any videos on the web! Nor are those great ads coming through. I have tried to download the latest flash, but it won't download. I am stuck and frustrated.

Can you be more specific? What do you mean by "won't download?"

Have you made sure you have the latest Flip4Mac WMV Player and Perian versions?

Did you go to adobe.com/flash and download the latest version? Doing so works for me just fine.
