please make sure mchat is up to date, this is an issue with what version of mchat you're using, not Vault. I verified with mChat source that the package does properly exist. Please verify that you do indeed have the latest version installed and that Vault says it's hooking it properly. If you have multiple copies installed this may be causing this issue. Otherwise, please refer to SimpleClans and mChatSuite for further help.
