So I've purchaced Cargo Commander, and I'm on a Mac/Apple. Whenever I try to download it, it does one of two things. If I'm on the INITIAL purchace screen, where I first bought it, it says for a few hours- Checking new liscences, and if I'm on the store page, it gives me a Black and White Circle, with B&W triangles in it. Then it goes to my Mac rainbow swirly circle, then nothing, my regular mouse. I can't believe it. Help!
