My laptop has recently had a hard drive replacement and I've had to reinstall the Vectorworks 10.5.1 software that I have. I am unable to start the programme as the dongle is not recognised as attached. I have downloaded and installed HDD_Installer_MacOSX.dmg but still no luck. I am currently running on MacOSX 10.4.11 having previously run on an older version. Any suggestions as how to fix this problem? Any help gratefully received!
