So... I connected the HX Stomp to the updater and installed the newest firmware 2.92.
Well, then I openned the HX Editor to start working on some presets.
First, on the preset list I picked on of the presets to move next to the other one that I wanted to edit. And when I tried to open it, it had cleaned all the blocks on the HX Editor but it showed them in the Stomp display. I tried to open the other one that I moved and it didn't open as well.
Both of these presets have IR loaded. Since
