Hi all. Has anyone experienced a problem with Logic not opening due to eRegistration error messages. Have purchased a URC44 interface, and part of the downloads for Tools for URC, contains the eRegistration Control Setup App. After I installed it Logic wouldn't open, and despite following all the Steinberg directions to uninstall it along with all associated files, it still remains a F***k nightmare. Imac 2019 Mojave 10.14.6. has now been restored to factory and a full Time Machine backup has been done. Logic is now opening and I have downloaded the necessary Tools and Firmware again, but hesitant to install again. Any help or advice is much appreciated.
