Embedded stats not working?

I have the embedded stats banner in my blog, however it has recently stopped working and just says 'no trips found'. If I click the embed this link on the stats page all the previews say the same thing. Anybody have any idea why it isn't working?

Thanks.

Hi Stumongous, not aware of any issues here. Can you send me a link to your blog via private message so I can have a look?
