“I can't download update” questions: Please read this

[Gasai Yuno]

The 4.5.607 update has been pulled from the update servers.

We've looked into this Microsoft Exchange encryption issue with the recent software update, and we know what's going on. The update has been temporarily suspended to allow us to address this. We anticipate the update to be available soon when it is ready, and it will take care of this. Sorry for the hassle, and thanks for reporting this.
