Yea, sorry about that. Right after the release we started getting some random reports of file corruption so we immediately pulled the builds and put the 9.1.4 version back up.
We've been slammed working on it. It took quite a while before we could reproduce the problem here. (That's always the challenge. More times than not, we have a hard time reproducing problems customers see)
We've found the bug very late last night (1:30AM) and are working on fixing it right now. We hope to have 9.1.6 ready for release Very Soon.
We'll send out an announcement as soon as we have the new builds ready.
