I have to agree with Marque. I've recently bought ZBrush 2 and an upgrade to C4D, both more expensive than the upgrade to V6. Both purchases went as slick and quick as you could hope. In the past year  I've also bought several other bits and pieces of software approaching the V6 upgrade price. With none of them did I ever have to jump through so many hoops as with e-on.

It's not just validating payment. What's with three long numbers to get it working - a serial number, an INST code, and an activation code? Even Microsoft don't do that! And even then their server gets it wrong and hands out the wrong numbers, as it did to me and several others apparently.

Frankly, great product but weird company. You'd think they were actually trying to make it hard to buy.
