According to Laszlo (https://cymaticaudio.com/topic/hello-3/#post-164666) “The main purpose of the forum is to exchange information with other Cymatic Audio users.” This feels like a problem that goes beyond your average users experience. I would advise trying the Contact -> Contact Support link up at the top and submit an official support request using their form.
That said, I sent a support ticket off a week ago and still no response. There has been no activity on the Facebook or instagram page since June of 2020. The 2 month old link above is the last time Laszlo posted in these forums as far as I know. It is suspiciously quiet. Feels like a ghost town.
