Latest version is 16.5; try it. Also check if you have the latest slave files from the installations on the whdload site.
Don't use a pirate key; it will make whdload unstable (own experience).
And please don't take this the wrong way but you seem to ask a lot of questions when there are really simple steps that may lead to solution. Like installing the latest whdload version; you don't really need a forum telling you to download that when you could have done that already?
