I updated the YEM to 2.6 - works just as the earlier version did. The change history (for 2.6) says the fixes were:
-------------
[V2.5.3 to V2.6.0]
Now supports the Genos V2.00.
Incremental installation of Expansion Packs using a USB flash drive called as "Quick Installation" is now available on compatible instruments.
Solved some other minor problems
-------------

I was able to install all the packs yesterday that are compatible w/the SX900. So far, so good! Love the board!
