I'm getting "invalid server response" when I try to spider a site

Question

I want to spider a partial website (to get documentation) but I am getting the error "invalid server response" when I start.
The site is perfectly viewable with Firefox, Safari and on my iPad.
Here is the section of the site I wanted to convert to PDF
http://quartzcomposer.com/patches
I'm using Acrobat Pro 11.0.03
Any ideas?
(By the way, there's no appropriate section for this aspect of Acrobat so that's why I just put it in this "creating, Editing...." section.)

OK, I interpret spiders as the feelers sent out by search engines -- a different use of the term. Anyway, I got the same error as you on both AA9 and AA XI. The other version was AA5 that simply said General Error. I was able to get the page into Acrobat around the back door. I downloaded the page to my harddrive and then opened the htm file in Acrobat. There are a whole lot of JS files called by the htm file. It did load that page, but I could not get to the next page. So the result is the same as printing to a PDF or using PDF maker in IE (I don't use IE). I tried the URL link with the htm file name and did not get the desired result. I suspect it is something that is non-standard but the browsers allow that is causing the problem. Acrobat sticks pretty close to the HTML standard as I understand it and it is where there are encryptions or other items that it messes up. I am not exactly sure what you are trying to get out of the PDF, but this gives you some idea of what to look at. I had looked at both the HTML source of the site and the site info to try to see if I saw anything strange. What I saw were a lot of calls to JS.
