Sorry for posting this here, I should to it in a
mailing list or something.
The problem is that the website
(http://sim-icq.sourceforge.net/) is not working,
instead the user is redirected to http://sourceforge.net.
This, besides obvious consequences, breaks the win32
installer, which apparently tries to download some
components from this site.
It seems to be something wrong with sourceforge itself,
but other sites which had this behaviour seems to be
correct by now.
