I suspect that you are trying to download it on your phone right? I just tested now and yeah, seems like Mixdrop is basically ad-hell in mobile. First of all, I want to say I'm sorry for that, I didn't know anything about it, since I tested only on PC (emulator, etc), but I'll look into changing the host to other sites pretty soon (Probably tomorrow morning it should be up on Mediafire, with no ads hopefully).
Thanks for the message anyway!
