Simplify3D User Forum

I have been trying to buy the software but the website won't continue to the checkout any help would be appreciated

Looks to be working for me, but if you still didn't get it figured out, then I'd contact their support guys: https://www.simplify3d.com/contact/

I had the same problem. I purchased it but then never got the followup email with the licence key, etc. I had to email their support directly and they were happy to sort it out. I had to do it again when they updated to v 3.0 as well. All in all, I have contacted their support several times in the last year and they are always very quick to reply and eager to help.
