Hehe, sounds like something M$ would do!
Like with Office2000 when they removed FoxPro file support - and all these companies were still using FoxPro powered systems with Access front ends. I had to make a registry hack just to get back to where we were with 97!.
It's always the little guy that suffers in these marketing ploys, pro modellers can probably get someone else to convert there models for them, so they probably use the default format - but folk like us end up suffering and wasting time on products that we spend our hard earned cash on.
