Hey guys, just wanted to chime in. I updated to v 1.7, and when I launch Quixel in with Photoshop it's initially okay, but as soon as I press a button on the Quixel widget Photoshop freezes. I don't get any error message. I previously had 1.6 and it was working fine. After it started freezing, I rolled it back to 1.5 and it started working again.
Awesome, awesome product, it's so much fun to use. Good luck guys, great work.
edit - forgot to mention I'm running Windows 8
