Unknown class, Something wrong (O_o)/

[Ovags]

Hello,
It seems like the script doesn't recognize the class when I'm logging in (Unknown Class, Something Wrong (O_o)/) and it doesn't seem to work properly, when adding a skill to the macro, it displays at first "Added: Macro Name: test, Type: 0, ID: 281000, Delay: 282" in pink and then "Error running callback for command "mm"", in the proxy log, it writes this error at this moment : [command] ERROR: TypeError: Cannot read property '1' of null
at String. (C:\Users\Ovags\AppData\Local\Programs\CaaliTeraProxy\mods\macro-maker-master\index.js:516:26)

What did I do wrong ?
