Oops indeed. I just happened to stumble across a careless bug in the Embedder code which meant that you could lose an attribute settings every time you disabled then enabled an embed. It was an easy fix, so I thought it best to post a new version of the plugin with the fix to prevent user frustration, even though this is the third version in 24 hours!
I highly recommend you upgrade as soon as possible.
I have also included a small fix for imports that should help make it possible to post embeds on your blog for others to use. I will probably put up a new post in the near future to explain how to do it.
Hopefully this will be the last release for at least a couple of days, not least because I have so things to do before Turkey day arrives!
