"Couldn't load plug-in"

I know most of you may not be computer experts, but I need some help with this.

Yesterday morning, I got on the computer to go watch some Youtube videos. I click on a video, and I get an error message saying, "Couldn't load plug-in." I looked for a solution, which was ending the process of Shockwave Flash Player manually, then refreshing the Youtube page. I did that, but it didn't work! I'm a Google Chrome user, and it's the only browser it occurs in. Anyone else who uses GC have another solution to this problem?

Oh I understand how you feel. That happens sometimes with me.
o don't know why it does that but I would just take a break from the computer.
