I tried several of the video tutorials and I get this same message in all of them. I went to utube and played several and they were okay.
I clicked where it says manage plugins but I just see the list of which ones are activated or not
Does anyone know why all of a sudden this is happening? Thanks

Can you post a link to a video you're having an issue with and the browser you're using?

Edit:
I just noticed you were having a problem with Jolie's videos. I checked with Firefox 33 and Chromium 37 with no issues.

I am using the latest version of Chrome and i have no errors with videos here Molly.

#1, this is something that has just started in the last few days.
#2, I checked a lot of videos besides Jolie's and I get the same error.
#3 I was able to watch it through the link gimper66 posted, so it must be one of my settings or some other crazy thing that can only happen with me.
I don't use Chrome. I use Firefox only.

Enter "about:plugins" in your URL bar and see if the Shockwave plugin is enabled.

To enable: open "about:addons", select "Plugins" and check the button/selector on the far right.

I just went into my addons and that one was disabled, but the funny thing, I didn't disable it. I would have had no reason to.
Anyway, thank you very much ofnuts, it is working now.

Ofnuts!

told you it was something simple. I already saw that it was disabled when I looked earlier and I thought it was something I didn't need and the default was disabled. O, well, I will never be a techie.
