haha. Looks like you uploaded a CSS File where it's expecting a Layout File.
The links for "Layout File" and "Menu File" are both supposed to be downloaded and used as the default, and from there you can modify things.
The Layout File is actually supposed to be an HTML file.
AFter that, if you wish to modify the CSS file, that should be uploaded to the Administrative File Upload part (and relinked in the Layout File accordingly).
If you aren't quite fluent in HTML, it's not an easy task at all, but that's one of the caveats that come with full control. If you want (if you don't have it backed up), I can restore your layout file to the default so you have something to work with.

I thought that maybe the case. Yes please reload my default
