Just checked the US forums, and it seems the same thing happened there. This is what I found:
"Unfortunately, when attempting to apply the hotfix, we ran into additional issues in testing. We don't have an ETA on when this will be able to be applied as of yet, but will be continuing to work on it. It's not a cut and dry fix unfortunately. Again, we appreciate everyone's patience while we work this out."
So yeah... Disappointing, but I guess we'll just have to wait patiently.
