The screenshot tells me that the scripts required by ISBoxer did not get installed to the Inner Space folder.

This means one of two things:
1. You did not install ISBoxer to the Inner Space folder, and therefore the required scripts got installed to the designated ISBoxer folder rather than the Inner Space folder
2. You unchecked the "required scripts" box during installation of ISBoxer, and therefore the required scripts were not installed

Assuming it's #1, you can copy the contents of ISBoxer's Scripts folder into Inner Space's Scripts folder.
