Well, got my Helix back this morning and it almost looked like the loop would have to be opened up again.
Powered it up and noticed they had updated the firmware to 2.11 so I downloaded the 2.11 editor updater and ran it. Software and drivers installed fine. Did the "hold down buttons 9/10 power cycle Helix" thing. Bounced PC just to start fresh, Plugged Helix into USB port and powered it on and then the fun began.
Sometimes the Helix showed up in Playback/Record devices, sometimes not. Sometimes unplugging/replugging USB connection gets it to show up. When it does show up 9 out of 10 times the Editor wouldn't see it. Tried USB 2 and 3 ports. Same issues.
After fiddling about for about 30 minutes I decided to try another USB cable and that seems to have resolved the problem I guess my original USB cable magically went semi-toes up by just lying around idle for a few weeks. Strange.
Well, fingers crossed that my Helix is now healthy.....
