BUG: Slash Command Error

[eTzmNcbkrng]

running /ctp with no arguments throws an error.
It should silently fail or print help text showing valid arguments.

12x ClassTrainerPlus\ClassTrainerPlus-0.7-beta.lua:836: bad argument #1 to 'lower' (string expected, got nil)
[C]: in function `lower'
ClassTrainerPlus\ClassTrainerPlus-0.7-beta.lua:836: in function `?'
FrameXML\ChatFrame.lua:4695: in function `ChatEdit_ParseText'
FrameXML\ChatFrame.lua:4356: in function `ChatEdit_SendText'
FrameXML\ChatFrame.lua:4392: in function `ChatEdit_OnEnterPressed'
[string "*:OnEnterPressed"]:1: in function <[string "*:OnEnterPressed"]:1>

Locals:
(*temporary) = nil
(*temporary) = "string expected, got nil"

Also, is there any documentation on how the import feature works? I couldn't figure it out so have been copying characters' individual SavedVar files.
