Hi Acajoun,
let's say you extracted act.jar and all other files in a certain directory lets say "C:actorstest". Next: place in the same directory any existent actors static file . Say that actors.static file is called actors1234.static or whatever name.
Go to programs> accesories and start the "command prompt" program. Navigate to the directory "C:actorstest". Navigation is done with the commands "cd .."
which moves you towards the root C and with "cd directory_name". For example in our case do repeatedly "cd .." till you are in the root "C:" then do "cd actorstest" and you'll be in your actors directory. Once you are there give command:
java -jar Act.jar extract actors1234.static
Similar steps when running the create, anyway hope it helps and don't hesitate to post if you have problems.
One important file which has to be present besides the actors.static is MapSize.txt,
see readme.txt

There's another way of executing the "extract" and create commands, using .bat files maybe next time about it...
