I recieved Turbo CAD 2D/3D V 9.2 for Christmas. I too went through the registations follies. I did not know that you HAD to be online when you start the program or it does not like to be registered.
So I finish playing around with it and go to the IMSI web site and try to register my product. I can not find 2D/3D V9.2 so I pick the closest one and it does not work.
I wait for the next day and remember to be ONLINE, fire up TurboCAD and it goes through the registration process. I found that the UNLOCK code on the CD case is the same as the web site so I think that it will be fine for as long as I have the program.
So far it is a good program. I just need to spend more time with it. I was able to get the 2D and 3D manuels from a really nice guy named Alan for the cost of postage. Thanks Alan. I have had a heck of a time trying to get some extra time to spend at the computer since I have been replacing the floor in my house.
