Monday morning, I hopped on Minecraft. It crashed. Tuesday night, I tried again, and it worked. But all my worlds, gone. All my servers, gone. All my texture packs, gone. It was like I just bought a new copy.

All my texture packs, gone
Minecraft does never delete texture packs.
Someone / something has deleted files from your harddisk.
