You just need to scroll past the understandable ranting of disgusted customers and the terrible answers by Microsoft support staff - you'll find an answer from "Windows Live John Dominic U.", that apparently helped out the guys in that thread that had that problem. Cliff notes: when sending an email, WLM assumes, that you use Hotmail anyway, because that's just how MS rolls, and creates an album online. Now when you don't use Hotmail or w/e MS ****, then that step fails, and it produces the error number you get, for which apparently 90% of MS staff can't tell what it means. The solution is to send it as an attachment instead of inline - or so I guess, I mainly skimmed that thread. But following that guy's guidelines seems to help.
(gem) Hvis du klikker på en persons navn, og så på afsluttede spil får du en liste over spil som er færdige, klik så på navnet på spillet for at få et sammendrag over alle disse spil, og til sidst på navnet på spillet igen så får du et spil du kan se på og analysere. (Servant) (vis alle tips)
