Can you send the full server log using a pastebin service? Theres probably some error at startup.

Thanks for the quick response! I think the issue was that my server was overloaded. I increased the Bukkit timeout by a lot and it worked this time. :)

Are there recommended Bukkit and/or Java settings for this mod?

Not really, MyWorlds doesnt really use a lot of memory. If you plan to create a lot of worlds, its a good idea to disable their spawn from being kept in memory, as that could use more memory than you may have. (/mw keepspawnloaded false)

Thanks!
