Welcome to the forum!
InkCut has not been maintained lately. I just read where some people are working on updating it. But unless you downloaded whatever they are working on, then what you have probably won't work properly (if at all). And if you did download this new version, you should contact the authors, for help.
Can you give us the link where you downloaded it?
What format do you need? It's possible there's another extension which will do what you need.
