It's strange, when I open the decks for Might & Magic IX in the client for online play, it says that the file format is incorrect. I've never had this before; I think we even played with these decks in Vegtam. I opened a deck for Might & Magic X, and everything is fine.
In general, their server is still running, and people are even playing on it, so everything is okay.
