Flash Help

[Apathetic Lurker]

I use Opera and have the latest version. When I went on Opera today I needed to upgrade my flash player to use Youtube. I uninstalled the old version, closed Opera and installed the newest version. Still have the same message that I need to upgrade Flash to the newest version when I go into Opera. No such problem with Firefox but i'm not a fan of that browser. Any idea what I need to do?
