i am having problems with jetload too
just keep clicking the " i am not a robot" and nothing happens
on chome there is no reaction
on firefox, a few spam popups opens up, like 3-4 new windows, and after closing them the button is avaliable, but nothing happens when clicking it
last week it worked fine
both the extensions and jdownloader are updated
firefox version is 3.3.7
chrome version is 3.3.6
edit:
just saw this topic:
