Hi I just called BOBCAD and they told me they would not register my 5 seats of BC21 anymore. I was so pissed ! I run MAstercam and Solidworks now days but I have old files with the CAD saved that cannot be converted. I understand not supporting it BUT I paid for the programming and they should either make it open source or give us a way top install it. Anyone else have this issue? I tried their 25 and paid for it . At that time it blue screened all of my computers. We never found a solution so we abandoned it. Bobcad could not fix it either so Bye bye to my old friend. I have used BC since 1995 and I was just floored that they threw away our relationship. I would appreciate any ideas or comments on ways to get the program running again. My Email [email protected] if you have ideas.
