..on Facebook. It says to click the button to download Adobe Flash if it won't load,which I have done, but it still won't load. It has done in the past,no problem. What could it be pls ??
Try watching a Youtube video. If all you see is a black rectangle (where the video should be), Flash Player isn't functioning properly on your PC.
If so, uninstall 'Adobe Flash Player Plug-In'. Then reinstall from here:
http://get.adobe.com/flashplayer/
(NB: I recommend deselecting the option to install 'McAfee Security Plan Plus' before downloading from that site).
