doesn’t work on C3D files

I wanted to review some c3d files with this on my Yosemite MacBookPro. The app comes up fine. When I open a file, a message flashes across the screen (probably an error message but it’s impossible to read unless you’re a Vulcan) and then an empty plane is shown. I tried some c3d test files from c3d.org and got the same result. I can’t find a way to show log output. Once I pressed some key and got an onscreen menu showing some choices, but none looked helpful for my situation. (Devs should make this feature more discoverable, or at least show a menu item.)

Maybe those familiar with Autodesk can work with this. But I’m certian it doesn’t handle c3d files and doesn’t tell me about the error condition in a useful way.
