Hi, i use a Helix LT and made the 2.81.1 Update.
 
	First everything was fine but soon Problems started. In my case i could not change the behaviour of my footswitches anymore, they  stuck in 8 snapshot mode.
 
	As someone mentioned i tried to do the update again, but the problem remained.
 
	The solution was simple, i just made a Global Reset and now everything is working fine.
