I know the package hasn't been tested on newer versions. I get this error when importing:

- exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> NHibernate.Exceptions.GenericADOException: could not execute batch command.[SQL: SQL not available] ---> System.Data.SqlClient.SqlException: Cannot insert the value NULL into column 'DataTypeId', table 'ucom12.dbo.uCommerce_DefinitionField'; column does not allow nulls. UPDATE fails.

This is probably because of some schema change in one of the versions since 6.5.

Is there any possibility of open sourcing the package?
