I'm more that convinced, myself, that the 'pt.eu.org' domains are to die, unfortunelly.
With the entity to whom the 'pt.eu.org' was delegated totally vanished from the Internet (I can't find them nowhere!) and the problem with the error that still pressists, I don't have any other option but to rebuild my whole DNS structure on other foundations.
Out of that, everything is going on, although with a lot to do.
But is good to be occupied, anyway.
See you all latter!
