I can’t seem to get vimeo videos to play. Do I have to be a logged in user? Do I have to download them? I’m computer challenged… 
I can bring up the link, it just won’t play.
Can you play flash movies? When the page comes up do you see the movie or is it missing? You have to click play, the videos will not automatically play like youtube. You can just click anywhere on the video if this is your issue.
The video link does not come up. The three little vimeo lenses are rotating but I get no video screen.
Still computer challenged…
You should use unicycle.tv 
Your Vimeo Problem sounds like a Flash Problem. make sure that you have the last version of Flash Player installed. Maybe it can also be a Problem with your Browser so test it with another one like FireFox for example.
If that don’t work, see above.
I reloaded flash player, and all is well again. Somehow??? (my son uses this computer) something got changed.
Thanks olarf for the help.
