Blogger Template failure

I adopted this template, Beckett, from blogger template because of its design. However the Cascading Style Sheets codes are not embeded in the template itself but are linked to a referal website which is having some kind of problems or something go wrong I don't know. As the result, the format of my blog is now unstable and it takes long time to open web pages. I am looking for other good looking and powerful templates for blogger, any suggestions?
