I think support has given every suggestion possible. Just wondering if anyone else figured out a solution on their own yet. COSMOS in Mojave (and some other OS’s too I hear) works upon install, then fails after reboot. Gives you that “Something went wrong. Please contact Technical Support.” message when it does it’s little start-up sequence.
I went so far as to delete anything Waves related from my system, folders, files, even Waves Central, and do a complete fresh install. Again, everything works great… until reboot, then Cosmos fails. My temporary solution right now is to re-install COSMOS every time I want to use it, which is far from elegant. At least it doesn’t have to re-scan everything though.
