Same here. I did what Line 6 is telling you to do. Download Helix Edit, install, install 3.6, Rebuilt Global, rebuilt presets doesn't solve the problem.
Froze twice on the same patch.
Another thing I noticed is that it is now very slow when browsing through the preset. If you turn the knob 2 clicks it only move by 1 preset.
Deleted all user preset, still.
Very disappointed that they would push that garbage to customers. I hope they will fix this asap.
This is now a 2,500$ piece of useless metal and electronics. I have gigs lined up...can't afford to deal with unreliable gear.
Thanks Line 6, I'll go back to what always works...analog
