If you have a M2xx or Fuze, you can ask me if it is possible to add support for that.
I'm in contact with someone who ownes a Fuze and who wanted to send me some sample files, but until now I didn't receive anything so it could take some time. But it is possible.
I don't know if it's possible to add support for the M250. Contact me via the Thanks-Button in the Program. But I'm in vacation next week.
@BryanKitts
If you recreate the database, export the ratings first, rebuild and import the ratings again (under Settings - Database), but I think Playcounter get lost.
With Rockbox:
I got these Memory Error yesterday too but could'nt repeat it today. In my eyes it is not an error of SansaMonkey

Try not to use the Rockbox-USB-Mode to be sure it has nothing to do with the connection between player and PC.
Finally I'm not that active in that forum anymore because MediaMoney is developing into a direction I don't understand (2.5 was so nice and stable). So if you have questions which are not answered in time here, contact me again via the Thanks-Button in the Application.
