Macs and Neuromixer

[herofukutu]

This is a numpty question I'm sure but I can't find the answer. I'm going to do a VJ tutorial for a bunch of school students and thought Neuromixer would be suitable. I've used it before and can load it on a PC. It loads on my macbook (I'm less familiar with macs) but it will not play files, even though it seems to load them. I'm obviously missing something really obvious and any suggestions appreciated. (I'm having the same problem with the pro and lite versions).

you need quicktime friendly files on a mac, so .mov or .jpg
tried those?

Yes. They're all files created on the same computer.
