SSMA - data migration step stops working mid transfer

Hi there

I'm migrating using:

SQL Server Migration Assistant for Access v5.0.9195

Things work great with some small tables, but doesn't complete when migrating a table with 100k rows.

I've tried 3 times, and each time the process doesn't get past the 50k row mark.

Is there any way to configure SSMA to reconnect to SQL Azure if there is a connection problem?

The log file says (repeatedly):

[Datamigrator: Error] [9416/9] [2012-02-14 12:09:26]: Exception: WriteToServer requires an open and available Connection. The connection's current state is closed.
 site: System.Data.SqlClient.SqlInternalConnection GetOpenConnection(System.String)
 source: System.Data
   at System.Data.SqlClient.SqlConnection.GetOpenConnection(String method)
   at System.Data.SqlClient.SqlConnection.ValidateConnectionForExecute(String method, SqlCommand command)
   at System.Data.SqlClient.SqlBulkCopy.CreateOrValidateConnection(String method)
   at System.Data.SqlClient.SqlBulkCopy.WriteRowSourceToServer(Int32 columnCount)
   at System.Data.SqlClient.SqlBulkCopy.WriteToServer(IDataReader reader)
   at Microsoft.SSMA.Framework.Access.SqlServer.DataMigration.TableDataMigrator.ProcessNode(IDataMigrationContext context, DataMigrationState state, XNode node)

Any help appreciated. If SSMA isn't robust to handle such issues, do I need to write my own code to do the migration?

Thanks
