I tweaked my infopath form by taking out a Lookup field that i no longer needed, and deleting the Data Connection, and now i can no longer submit my form. I get this error:
The SOAP response indicates that an error occurred on the server:
Server was unable to process request. ---> Object reference not set to an instance of an object.
i looked in the log and found a bunch of errors - this one seems to hold a clue:

any idea what i could do to further troubleshoot this?
