Scnsnap S300M stopped working with Yosemite update

I recently updated to Mac OS X 10.10 (Yosemite), and about that time my Fujitsu Scansnap S300M stopped exporting to Devonthink Pro, and in fact stopped working at all. I have Scansnap Manager Version 2.2 L15. Fujitsu has an update to L16, but only lists L11 as the prior system. Is L15 proprietary to Devonthink, or can I just download the most recent version of Scansnap to recover my OCR function.

Okay, so I was impatient, and my computer is backed up with Time Machine. I downloaded the L16 update, and that cured the problem with Yosemite. Back in business.
