Imandix Cover Pro help

Hey, folks -

I bought Imandix Cover Pro, and whenever I add files for a collection, it shows the covers as solid black. Probably just a setting, but I can't seem to get it figured out. Single case projects seem to work fine. Sorry if this is not the place for this, but help for this program is scarce, so any guidance is appreciated.

Screenshot of the problem:

EDIT: I figured out that it thinks that the Blu Ray cases are not valid for collections. Anyone else have this problem? Until this is fixed, I can just export the single PNGs and superimpose them, I suppose.

After fiddling with it for a while, I was able to make a custom object with the right dimensions, but it does not have the extra blue plastic at the top like a normal case; it is just the cover area with a small outline.

This is beta, obviously, and I think the collections portion could be fleshed out more. There is also no option to adjust the lighting, and if you rotate one of the objects to show the reverse, it is very dark. Perhaps these issues will be corrected with future releases.
