Hello. I performed a couple of searches but this topic didn’t turn up.
I downloaded the trial version of Zbrush 3.1 today. The first time I used it the ‘enter serial number’ box popped up. I obviously haven’t purchased anything to recieve a serial number, but I noticed the ‘activate later’ option gave 30 day’s grace, so I figured that was the proper option for the trial and clicked it.
My first session lasted a couple of seconds, when I decided I’d better read a few instructions first. Now, a couple of hours later, when I try to start Zbrush I’m informed my license file is faulty, and it won’t start unless I contact Pixologic and give them my serial number…
