If you need the data, if you downgrade the SDK, you should be able to access the data so you can export it to reimport. We've seen this before with version switches. More likely than not, it's related to the fact that the datastore stub (local_db.bin) is just a serialized Java object. When we try to read in the object from the file an fail to deserialize, we just start with an empty datastore.
