I am trying to understand the basic work flow of using Malzilla , and therefore doing the tutorials. But already in the first one, where you actually get to do something I am lost as it doesn't work for me at all, even though I follow it step by step.

In the first paragraph where you have to concatenate the string and then translate it using the MiscDecoders->DecodeUCS2, I am getting not printable chars as a solution, after concatenating and using the decoder.

In the second paragraph where you are told to run the script after adding the function-call at the bottom of the script, the Decoder tells me that he cannot handle the arguments.callee.toString() method and therefor wont run the script.

How outdated are those tutorials and how can I get them to work?
