I just found a potential cause for this issue on Mac - changing your computer name. If your computer name has changed, changing it back to the name you see under the 'authorised devices' section on your Line6 account can fix it.
 
	 
 
	Even if you think you haven't changed it, double check - MacOS will sometimes change computer name automatically if you're on a public WiFi network with another computer of the same name. E.g. mine has the default name 'MacBook Pro', yesterday I was on public WiFi and it automatically renamed itself to 'MacBook Pro (2)'.
 
	 
 
	Today I booted up Helix and got the same problem (Error 1116, yellow pick icons, presents not working), I changed the computer name back to 'MacBook Pro', restarted the Helix plugin and now it's working perfectly. No need to factory reset or lose my presets.
 
	 
 
	This may not be the only cause of the issue, but I hope it helps some of you!
