Oh good, post your launcher.log from My Documents\Blockland. The missing Slate might be the Halloween version of Slate, and if you haven't updated yet, I'm sure Badspot would like to know. Once Badspot has gone over that, you can fix it by deleting the cache.db from My Documents\Blockland. But let Badspot see the launcher.log first, since I couldn't show him for my update problem.
