Just remembered something.

Kobo changed an option in the database. The have changed from journal mode to "WAL". This should mean better performance and I less likelihood of corruption. But, the Windows version of the Python SQLite library that the KoboTouch driver used did not support this journal mode. I needed to change the driver to use a different Python SQLite library that does support this journal mode. This was released in calibre 2.63.0.

What this means is that you cannot use a version of calibre before 2.63.0 on Windows with this firmware. You will also need the latest versions of the Kobo Utilities plugin and KoboTouchExtended driver if you use them.
