Ah yes, that solves it :D
Thank you William for the fast response!

One more question: I've read in the faq that getting ASP etc. can be a high
load on the server. I've now limited the connections to 1 per second.
Will that be sufficient?
And I don't know what your knowledge is about website coding etc. but how come
this website seems to be using some sort of login through twitter? Really goes
beyond my mind.
It's the link HHTrack showed through the proxy URL capture. And it only works
when I add the username:password method.
