I've just updated to 2.14.1 and this error pops up constantly:

I can't revert to a previous WA version, the error still persists. I can't even open the Weak Auras window, the /wa command doesn't work, no chat message or error or anything at all. Everything was fine a few hours ago when I logged out for the night, so the only thing I did in between was to update WeakAuras this morning before logging in (I usually update once a day in the morning, if there's an update) :\

I'm attaching my WA file (it uses some custom textures, but I guess they'll show up as green squares, if anything).

WeakAuras.zip

I get a different error, but I also can't open the weakauras window.

@timmywil that's unrelated, create a new bug report and include your settings please.

I take it back. It was an installation issue.
