I've done it, it was the new firewall which was silently "isolating" opera so everything looked fine on paper but it was sending an empty file. It was hard to spot
I have no problem continuing to play, I'm just sorry I don't think I can do any good now with 2 early stales in a row due to technical problems - which is a pity because I loved the theme of the game.
EDIT: oh btw of course thanks for the delays Truman
