Vimeo Image Link does not display, only text…

I’ve never had this problem before as I’ve been able to post messages on my Blog and then adding the vimeo video link text so that once it’s published, the actual Blog will showcase the vimeo link and run it on the page. But for some reason, I wrote my comments and then added the vimeo video link above the comments and it won’t show the video like it has before. Check out my blog and you’ll see how my blog posts are displayed… and that’s the way I want it. But I can’t do that anymore… what am I doing wrong?
