Tags still not working after I moved the blog

I did the flush and no luck, here is an example. Bottom of this post, http://wellsaidcabot.info/toy-drive-2012-vid/ I clicked on the tag mcjunkin red man corporation looking for all other post on this company. In stead of a list I get this error page: http://wellsaidcabot.info/tag/mcjunkin-red-man-corporation-mrc/

I recently moved the content on this blog from another blog. Could there be an issue since it is a new domain name?
