just tagging a +1 to this problem.
I use Ableton and when I initially installed Helix Native Demo it worked just fine. The second time I went to load it I had the same event occur ... the beach ball of death. I also wrote to Line 6 and received the same email as 'Petes63strat'. Unfortunately for me it did not fix the problem. Still waiting to hear from Line 6 whether they have any additional steps that I could follow.
