Forgive the construction

I'm not sure what's going on but my blog does not want to accept the template I'm trying to apply to it! It was working perfectly fine before and I was loving it but now, well now it just seems to be flipping me the bird and laughing at me. So please excuse the mess while I sort this out. If it really won't take one of the new template designs for me then I'll revert to the old set up but I don't really want to do that....
