Thank you copy and paste

There is a thread in this same Apps. forum on this if you need more help, try and scroll down half the page...I think it's the same info though

It's pretty simple - all you really need to do is download
http://formymac.com/MR/plugins.zip, unzip it (it'll unzip to a folder named "Internet Plug-Ins", so don't unzip it in your Library folder, else it'll replace your "Internet Plug-Ins" folder), and copy the "Flash Player.plugin" file from that unzipped folder into your "Macintosh HD/Library/Internet Plug-Ins" folder.
You might or might not want to save the new Flash plugin you'll be replacing, but I doubt it.
