Fred with "extract" you get the out-files. The inverse process, "create", uses the infiles as input files. Try this:
1.run extract
2. rename all outfiles to infiles for example outBuildings.txt to inBuildings.txt
3. run create
It should work but:
the inWing.txt (the bridges) should be non-void. So if the original map had no bridges the outWing.txt will be 0 KB. If you rename all out to in and run create it will not work. So in your case it's not working since you have no bridge. But you can add a bridge either in FMB map mode or do this:
Copy the text below and paste it into notepad and save it as inWing.txt in the folder you run the actor tools for your map. This inWing.txt is just a bridge somewhere very close to the border of the map. Then the create should work.
One more thing make sure there are no blank lines at the end of each in-file, that's another reason i know for "create" not to work...So here's the inWing.txt
