@chanur - not your fault, I get download issues myself as well - on all my PDF's, using Adobe Reader.
Something screwed up my site (again), which gives me something to do for the weekend :(
EDIT - the download manager misses 8kb in all transmissions, what the heck! Bug in the Wordpress plugin I guess.

In the meantime, the webpages are available (you can walk through them using the Articles section at the bottom of the page).

Thanks for reporting this!!

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.

visit www.aRtBeeWeb.nl (works) or Missing Manuals (tutorials & reviews) - both need an update though
