My wife's laptop Acer OS Win8-1.

Whilst playing a YouTube video the following msg. received:-

ďAn ActionScript error has occurred. Error #2044: Unhandled security Error: text=error #2048: Security sandbox violation: http://fuse-client.mirra. Io/fuseclient.swf ? gid=266 cannot load data from about blank at com.hinish.examples.vpaid: Player/fetchVast()
at Methodinfo-97()
at EventDispatcher/dispatch EventFunction()
at EventDispatcher/dispatchEvent()
at VRLLoader/on Complete()"

She cancels this but, whilst playing video it returns. I am writing this on my desktop OS Win 7-64 Home as I have no experience with Win .

Assistance very much appreciated as she is unable to watch her YouTube.
