Scott,
I assume you followed the MM instruction on how to add the Stonfield classes to you project, so make sure you have in the app data folder the following files:
a. App 3 DB files (.DBC, .DCT, .DCX)
b. Stonefield metadata files: CoreMeta.* , DBCXReg.* , SDTMETA.*. (you need to distribute these files as well)
It should work with these files on you app data folder.
