Migrator for Notes to SharePoint

weird cookie expiration issue

Hi,  

We are running our quest jobs through the command line.  However we keep getting the error below.  What is this Cookie Expiration?  I was thinking maybe it is the thing preventing us from the migration.  

General: [General] Cookie Expiration, Cookies expire 10/11/2017 9:06:23 PM 
Migration Failed: Could not load file or assembly 'Quest.NSP.Transform.Notes' or  one of its dependencies. The system cannot find the file specified. 

thanks.
