How do I solve Error #2044

Hello there,

I hope this is the right section.

For an unknown reason after I updated to the newest version of Flash Player, I started getting errors while playing videos on YouTube.

I use Safari and Firefox and the poblem persists on both browsers. Just e few seconds after I play a video, that error appears on my screen and the video stops :

Error #2044: Unhandled SecurityErrorEvent:. text=Error #2047: Security sandbox violation: LocalConnection.send: s0.2mdn.net cannot access https://pagead2.googlesyndication.com/pagead/gadgets/overlay/OverlayTemplate.swf.

I would appreciate any help on how to stop that annoying message from appearing!
