Got it working.
I installed the the library file, removed usb, touched ok and power off/on. Everything worked but no fx palettes. Then the same for OS. But it didn’t boot up. Tried holding shift/F1 and other combos in the manual, nothing.
when I inserted the usb drive to a PC, it showed errors and didn’t even format. Unfortunately, all my latest showfiles were on that drive, stupid me.
Took another usb and did recovery and got it booting again. Now I just have to remake a 100+ cue show with three universes of stuff.
I haven’t checked the fx palettes yet.
