I switched to SuperSu last night and it didn't solve the problem.
I am actually on Stingray Cornerstone nightlies. I reverted to a nandroid of Nightly #15 and the problem went away. Installed Nightly #20 on top of 15 and the problem is back. It's the same with books, music and apps; I get a pop-up that just says "error please try again".
I don't have a problem updating apps and if I purchase music on another tablet it will download to my xoom; I just can't purchase them on the Xoom.
I may try the latest Stingray nightly without Cornerstone and see how that works.
Edit: Oh, by the way, "Face Unlock" quite working about the same time as well.
