On the 16th I used youtube fine, jumped on the net on the 17th of this month and went on the widows update and updated windows (I was wondering if this affected it) and I was told I needed to use the new version.
So I follow the instructions and download the new version.
Go back onto youtube and other various sites and it still says I need to have the latest version.
I have checked the add ons and adobe is enabled but it still not working.
I am using IE.
What Windows version and edition?
What IE version? IE9, do you have ActiveX Filtering enabled?
