It appears to me that everything transfers with the license including extra seats. If you have two seats, then both seats will transfer under the one license. But it really isn't clear if BobCad charges $100 per license or just $100 for the main one and then the rest transfer as part of the deal.
I thought you had a couple of weeks to return the software to BobCad for a full refund.
What is wrong with the software? Evidently you don't like it since you already want to get rid of it. (edit: I see your "for sale" posting in this forum.)
Personally, I think you are jumping the gun on getting rid of it after one week. I'd play around with it some more and watch the videos and maybe something will "click". It did with me. I've used DolphinCad-CAM, Alibre, TurboCad (plus the CAM plug-in) and messed around with SolidWorks (one afternoon) and I can tell you all of them have a pretty good learning curve. You can always post questions here too.
