AVE Ezymix1? What on earth is this thing?

So, the grand-kids have always known I've had a soft spot for making music compilations, and bought me an AVE Ezymix1 for Xmas because they think I'd be a good DJ. Oneof these things:

Apart from some Youtube videos from this AVE / DJ City outfit (same company) showing off the larger Exymix controller (which bears a strong resemblance to an American Audio VMS2) I can't find diddly-squat about it on the web.
It's about as bare bones as you can get - the controller in a cardboard box, a "manual" consisting of two uninformative A4 pages stapled together, and a CD with Mac & PC versions of Cross DJ LE 1.1. No setup instructions, no how-to's, no what-plug-goes-where. Some googling shows an "EZYMIX.PDF" buried away at the DJ City website, but whatever it is, it isn't a PDF, because it's un-openable.
Worse, AVE never answer emails. In fact, if I email them with the receipt flag set, I get a message back saying my email was deleted un-read.
Chasing the only other brand name in the box - Mixvibes - has led me here.
Now, what do I do with the bloody thing? Where do I go from here?
