before re run the wizard, make sure that you delete the pages that had been created the first time.
When you get this error? does it happen while createing the pages? Or while setting up the pages in the wizard?
Are you using one of the Presets? Or using the New from blank option?
Selecting the option to create the table? or using your own table?
If using your own table, can you provide a SQL dump of the structure please.
