Scratching my head here, would appreciate any help! On a Macbook Pro 15" Retina with Lightroom CC 2015.1.1. All modules work just fine but when I select the print module I just get a blank, empty center screen. The filmstrip and top bar with the module labels, but no side panels and nothing but an empty center screen. I'm stuck-any thoughts? Attaching a screen shot if that helps.
