# Common Questions¶

## General¶

### Why don’t any commands work?¶

If no commands work, it may because CraftBook failed to start:

• Make sure that you are running Sponge (or a server software that supports SpongeAPI). Use the sponge command in console or in-game and make sure that the command exists.
• Make sure that, if you had downloaded CraftBook as a ZIP file, that you have extracted CraftBook.
• Make sure that you have the proper version of CraftBook for your version of Minecraft.
