Thank you. But your link seems to have the same exactly problem with TCP port 4000. So it looks like a wide-spread problem.
Doesn't work for me either. It tries to upgrade to the new version but gets stuck at the jre install step. This is the first time I couldn't log on to IB. I had to use the stand alone version. Hope they fix it soon.
