El mensaje “CDBase está bloqueado por otro Usuario”
this message simply tells you, that someone else is using the CDB. In most cases it is sufficient to close SOFiPLUS and SSD and delete .cdb and.sdb.
If this doesn’t work, simply save the project files *.sofistik and *.dwg in a new folder and start again.
Hope that helps.
