How to set up Parcel Services - Batch reporting

Hello,

I setup Parcel Service according to the manual. However, I keep getting an error message "Given Key was not present in the dictionary" 

When launching from the Manage Package Group, I got error message "Summary: Error processing Data Management Step 'ShipPackage_OPS'.
Unable to execute Business Rule 'OPS_ShipPackageUsingID'.
Unable to execute Business Rule 'CV_ParamHelper'.
The given key was not present in the dictionary.". 

What am I missing in the setup? 

Thank you for any help you can provide.
