Tonight's update (4.1 apple 1, downloaded automatically from Curse) is throwing all kinds of errors. I have 744 errors along the lines of what's shown below. I am seeing this on multiple characters (although they all share the same profile).

Re-installed and it seems fine - might just have been a bad download...

Ah well, it got me to register here, so there's that. Thanks for the great addon!
