Data Migrator v1.33.6.0 - Hlimit does not belong to table ReinsuredLines

When trying to import a reinsured lines questionnaire I receive the following error message:
System.ArgumentException: Column 'HLimit' does not belong to table 
Install Alps Data Migrator v1.34.8.0
Also check the Reinsured Lines spreadsheet. Highlight rows 14 &16 right click and select 'Unhide' Check that Hlimit is listed in the spreadsheet.
