Saving a creation

hey i have a question. I created something and I want to save it so i can bring it into a different map. How can I do this. I downloaded advanced duplicator but it doesnt work. When I click save and type in a name to save it as, nothing happens.

Download wiremod, via SVN, from this tutorial. It has an up to date, working Adv Dupe in it.
Not to mention wire in itself is infinitely useful.

still cant save any of my creations.

Make sure you remove all old versions of Wire and Adv Duplicator before using SVN.
