As the title says, if you still have this problem it's likely this update has fixed it.
Thanks to everybody that notified us of the problem, and particularly to Steam user (ナルト)narutoo999 for helping us figuring it out.
Apparently it's crashing for a couple of users. That's a different problem altogether and we're investigating it. If NaLo crashes in your machine, try closing SteamVR and then reinstalling NaLo.
We've also fixed an issue with Cosmos and made a change that might make HP Reverb G2 compatible, although without adapted profiles. If it works you'll have to change the profiles to change them from joystick touch to something else. We'll finally receive ours in a few days so we'll be able to ensure compatibility.
