I know the Crawl Test reports are cached for about 48 hours so there is a chance that the CSV will look identical to the previous one for that reason.
With that in mind, I'd recommend waiting another day or two before requesting a new Crawl Test or just waiting until your next weekly campaign update, if that is sooner

Something else I noticed is that the site is coming back with quite a few errors when I ran it through a 3rd party tool, W3C Markup Validation Service and it also was checking the page as XHTML 1.0 Strict which looks to be common in other cases of 406 I've seen.
