Flash stopped running - Chrome, Windows 8

Hi,
Yesterday all was fine..today I have a problem with Flash, I didn't install anything or updated, so I can't understand what happened....
I have windows 8 and normally i access to chrome through windows 8, i played video, flash games, all worked fine.
Today, when I went to youtube and a message appeared -> "The Adobe Flash Player only works in the computer" .... I guess my laptop turned into something else during the night.... -.-'
I can't play videos, flash games or access many websites.....don't know why....can you guys help me?
Now I'm running chrome through the desktop, and everything works fine, but i really want to access through windows 8 like I allways did....

Thanks!!
