I've checked the Digit website and there are messages about this in their forum. Apparantly serial numbers are not being issued for the C2 demo any more due to the release of C3. They suggest trying out the C3 demo instead. Yes, it made as much sense to me. LOL I've seen wonderful work produced in C2 but I'd really need to try it out for myself to be sure that I was making an informed decision. No reply from Eovia yet but I think I'll try ringing their UK number tomorrow. Thanks for replying, mmoir. :)
