I've been using vectorworks for the past year+ and It recently asked me to update my proof of enrollment. I couldn't do this because I'm moving and still don't have any proof of enrollment. I called tech support and they said they would accept my old Proof of it anyway. Which they did. Now about a month later it says my serial number is invalid and when I re-input it, it pops and says, "your license has expired." It works on my other laptop that I just used the other day. It'd be extremely helpful if I can use vectorworks on my laptop again as it's much faster then my other laptop and much more portable. Help! TIA!
