I keep getting 500 internal server error on archive.org for importing HTML document. i opened the URL in the error message and site said busy, try again later but it never is any good no matte how many times I try. It looks like I have to 'borrow' HTML versions but can't see why.

Here is error:

Any hack of python in Calibre or info re registering with archive.org to be allowed to download the HTML version of the books would be good as I am a programmer and can write Python otherwise I read the book on the URL as an HTML directly on their site but not as an EBook in Calibre.

I have not upgraded as Calibre in later versions has problems with flickering ebooks due to Qt library changing and only Windows 10 being supported not Windows 7.
