BTW, everything else seems to work. i can create waypoints, the full GUI appears and works, and i can place blocks.

Please note that i can destroy the blocks.. just nothing is dropped for me to pick up when i do.

I just deleted the launcher, then reinstalled it. Now everything seems to be working fine. Also since i didn't delete ant files, it kept all saves and files. Hope this helps others looking for a solution.
