Oh, how sad. The website isn't there anymore! Hopwever, thank God it can still be accessed at
www.archive.org You can put i any web address and it will show you the history. Type in
www.ardalambion.com and go to the last date listed to see the page. The links I'm checking still work. Download everything you can. Hopefully
http://web.archive.org/web/200306100...dalambion.com/ will take you right there. I tried getting the dns info and it says information on the domain name isn't available right now. Maybe the domain just expired?
Download the Quenya courses. It's 20 courses, but very good.
I'll write more tomorrow.
