|You need to show us the code you are using. So you are using the msdn private pool sample as your database but have you actually checked it?
Did you try the entity sample to check the database is working?
I can't tell if the database is empty for example and you haven't enrolled any fingerprints so you have no pool to match against.
You are reporting a config error which usually means a database problem. Can I ask have you tried using the WINBIO_POOL_SYSTEM it is a little easier and at this stage you just need to get it working?
