Hi Dan,
I've sent you an email directly. For other readers who may have similar questions, another reason that it can take a while to get the data to CRM to reflect the current email statistics is if there are performance issues in CRM. When we synchronize data, if there are any errors or delays in the response from CRM, our system will retry the synchronization periodically. As CRM permits, the data will then be synchronized. In addition to delays in getting updated data, you may see symptoms of SQL timeouts in the Error Trace (under Settings in CRM, on the ClickDimensions Settings page), in which case, it can be necessary to perform some optimization of the SQL Server as described here: http://help.clickdimensions.com/considerations-for-crm-and-sql-server-performance/
