I was so silly/New problem

Hi there. Remember when I told you all about the rpoblem with the Smash bros 3DS code? Well, last night, I went to Gamestop to go get for myself a new Smash bros game. When I talked to the cash register about it, she told me that the secret code was actually hidden behind the game cover artwork all this time and not in a panflit. So I never did threw it away in the first place. So anyway, I typed in the Smash Bros 3DS code in my club Nintendo account and now I'm one step closer to downloading Mewtwo for free. (and maybe get for myself free smash bros soundtracks too. XD) Sorry for the panic everyone.

But....now I have a new problem. I can't view Youtube videos or any kind of video on Mac safari anymore due to this Blocked Plug in I keep reciveing. I tried to download Adobe flashplayer 3 times, but the problem is still there and not fixed. I'm not too concerned with the problem since I can still watch videos using Google Chrome. Bu this is really puzzling and annoying. Am I getting a virus on my Mac or something? Can someone please tell me what is going on here?
