I un-tar'ed the file and saw that it contained three files:

default.xsl
default.css
default.js

The first two (default.xsl default.css) were present in Charcoal's file. The last one (default.js) was not.

The first one (default.xsl), I placed in the root directory in place of Charcoal's file. I noticed that your version was significantly smaller, but did not check it in detail as to why.

The second one (default.css) was in Charcoal's "images" folder (based on his zipfile), so when I un-tar'd yours, I put it into the same place, replacing Charcoal's file. It, too, was significantly different in size.

The third files (default.js) did not exist in Charcoal's installation. Since charcoal has a similarly-named file in images (jscripts.js), I placed it there, assuming that's where it was supposed to go.

I get the same exact error on the Broceliande playlist.

I tried copying your two other files up to the root. Same result.
