It will happen; you use the exact same launcher as me, but you only provide one; so there's no fallback to go to if that fails. Missesippi1 I located the issue, and it's on my side (partly). It's due to the bad way batch files handle naming, causing it to stuff up. I will submit an update shortly. Any issues, check the FAQ on the BukkitDev page. If I haven't addressed an issue, request a support ticket. EDIT by Moderator: merged posts, please use the edit button instead of double posting.
