You have set all this?
Economy: For CMI economy to properly work you will need one of two solutions:

1. Is to use recompiled Vault version from HERE which has direct support for CMI economy and will have best compatibility with other plugins.
2. Use economy injector from HERE which will add CMI economy support to any Vault build.
   Both methods are valid but second one can have small issues with plugins which would tend to load straight after Vault loads and before injector himself.
   P.S. Don't forget to enable Economy in config file.
