Last week the Salesforce connector (SalesforceDLL.dll) wasn't connecting to Salesforce because of some API changes made by Salesforce.com. That was resolved by them and I was able to connect again.
Now my problem is, I query the data and the values all come back as NULL. It's importing the correct number of records for each table, but every value in every field is NULL.
I confirmed that the DLL is querying and retrieving correct values from the Salesforce API by using a tool called HTTP Analyzer to inspect the XML response. Maybe there are still version mismatches between the DLL and the newest Salesforce API?
