Adobe flash player wont work and facebook page of it's face.

Hi guys had some great help from you a while back but need some more pleeeease. I just went to watch something on you tube and it won't work anymore. Says I need to load adobe flash player. (which I did) but still dont work??? Also facebook is playing up...ie: somethings (pics etc) are not where they are suppose to be on the page. Weird. I removed old version of flash player first and then loaded the latest one i tried that a few times(even lowered my security settings and tried again) Looking forward to your reply.
