Poseidon registration for 3.2 Community Edition fails

This problem was brought up on a gentleware forum and one of the kind company folks posted a license key there that allows 3.2 to work for another 6 months.

They explicitly wanted everyone to switch to 4.0 as soon as possible, though. For that, you'll need the svn trunk from archgenxml, as that includes poseidon 4.0 support. (Or the upcoming 1.4.1 archgenxml bugfix release).
