we have draftsight 2020 now (from last year), just got an email that 2021 SP0 is out, so i installed it on my PC, but it's looking for a license. is there an new one? we were told that the solidworks license is the same one and its built into it? I guess not?

UPDATE - the version is Draftsight Enterprise and it uses a license file from the server (concurrent users).  so unregistering a pc is not really an option, since it says we have 5 license, and there are 3 available, and still says "cannot obtain a network license file"?
