Solved: FAILED TO CONSTRUCT REFERENCE error

Hi, until yesterday I've been using the Quixel suite just fine. Everything worked. Then I kept getting this FAILED TO CONSTRUCT REFERENCE error, and I can't use the suite. I updated Photoshop, I'm using Photoshop CC v.2015.5.0 and Quixel Suite v.2.0

Any ideas of what to do? After I click OK on the first message, Quixel appears to open fine (but it asks me to locate my Photoshop.exe and restarts it), but when I click on DDO, this message comes up continuously. Clicking OK only pops up a new one. Help!
