If it isn't using relative path coding to the /data and /runtime folders then it is indeed coded wrong. Blue Tree Studio has a lot of products out though, and they are usually correctly coded. That one I don't have so I can't test it myself. Have you tried contacting the vendor?

The only oddity I see in the file list is this:

RuntimeSupport LOCAL_USER_Recording_Studio.dsa LOCAL_USER_Recording_Studio.dsx LOCAL_USER_Recording_Studio.jpg

I have no idea what that is about, but it looks quirky. Everything else listed in the readme was pretty standard, the geometry files are all in /data and the textures are in /runtime/textures.
