The URL above does not exist anymore, because Christian didn't like the high traffic on his server and as he wrote it was experimental only. I plan to check all parts of code for 64bit issues within the next two months. So please be patient.
No good news. 64bit support won't be for 1.x series due to lack of time. Because the whole program is just to large to check it in a few days. 2.x is expected next year (rewritten from scratch).
