Have you PM'd Randy directly, he has a user account here as well as at PlanIt3D. I think his username at both sites is RandyR. He's quick to help resolve any problems he can help with. I'm sure he can still get you signed up (or verified as signed up already) and into the course. It was well worth the cost and a lot of fun so I recommend persuing it instead of going for a refund, but that's just my opinion. Good luck with whichever route you take. :)
