Same thing happened to me yesterday at soundcheck, Sea World Orlando. Had to run to GC and buy another Helix. This is after running it every day for a week, playing through it, and turning it off at the end of the day, just to make sure there would be no problems on the first gig in 15 months. This is after updating to 3.10 almost 2 weeks ago (yes, I went through 3.01 first) Definitely not my first update, as I've owned my Helix for 5 years now and have relied on it for touring for the entire time.
