Hi there! Have the same problem here, I was playing, then suddenly all my presets just dissapear and this message pop up: "Failed to get preset names Operation Failed due to DSP overload (code -8611)"
I have the 2.92 Firmware since the update came out and not have a problem at all until now.
Running on a Windows 10 Pro (1909).
My mail if somebody can help: clasesandrescastro@gmail.com
Thx in advance!
