Sure there were a few issues previously that eventually resolved. But now, just look at all the support requests going unanswered. I've had many of the same issues, including gallery creation/thumbnail creation since last update. Can't import zip files anymore. Really can't do anything.
So I think, maybe I'll uninstall and try again.
At least it left images on the FTP site, but wiped out all 82 galleries, images, descriptions, everything in admin area.
Now since I have to re-enter all that info, guess I'll switch to the wordpress gallery. At least I can get the images easily for use in posts.
