I have p5 but have never used it because I get the impression that with all the bugs there could be a steep learning curve, and I have not had time to deal with it. But I wanted Shade so I decided to take advantage of the $129 combo on the upgrade offer. I did not complete the order because they asked for a serial number, and I don't know what that means. Could it be sealed inside the P5 disc, that I have not opened? or do they mean something else. I never registered. I wrote CL but got no answer. The whole P6 business looks so confusing in general that I want to understand what I am doing. Also, if I do get inside the ordering system once I figure out what they mean by password, do they give you the choice of a real paper book and discs in a box? -- which is what I would prefer. You would think that all this would be more clear on their website. And anyway I am wondering if all this trouble is even worth it. Perhaps for just a little more I could get a better modeling program, and perhaps P6 will be as buggy and hard to learn as some of the messages here seem to indicate P5 was. I am a bit slow with this stuff, even though I enjoy it a great deal and have loved to play with P4 and Vue 4. So on top of everything else, I am wondering if P6 and Shade are worth not just the $129 but the trouble of ordering and then learning a new poser program. Also, I recall some comments in the forum about CL getting orders wrong and not responding to customer problems with orders etc. Any red flags here or was all that worked out and is everybody happy now?
