I´m working on it, another problem being that today is like only day of this month I got something to do that requires me to leave the house for the rest of the day. Naturally, the guys I usually play simultaneous multiplayer with didn´t have time for doing that the last weeks but they told me they all have time for it today. Hooray for timing. -.-
Edit: Well now that is weird. I just pressed OK in the password popup without entering anything, and lo and behold I could move my units like in a normal game. I then pressed Escape and gave me a password via 'Your Details', leading to the game doing the same thing as before, claiming my turn was over and I should send a non-existing save to Eclipse.
Then I loaded the game again, without entering a password at all, neither at the beginning nor in the menu. I could play my turn like normal, press enter, and now for a change there really is a save for Eclipse. I´m just going to send it to him now.
If I got this right, I may never set a password for myself?
