I am following the official OpenERP tutorial online and I have created a database in which I installed the applications Sales Management, Purchase Management, Warehouse M., Accounting and Finance, eInvoicing & Payments, Assets Management and CRM.

However, when I try to import a Leads database using Sales > Sales > Leads, clicking the Export link, exporting the same fields of the only Lead that I have in my database (I'm not sure I do the right thing), creating the CSV file named crm.lead as an Excel file in the My documents | Downloads and next I clicked on the Import link, I chosed the file crm.lead.csv that had been saved automatically in the My documents | Download and I tried to import the Leads database, nothing happens.
What am I doing wrong? Have I skipped a step? Is it a configuration problem of OpenERP 6.1?
Thanks for your answers.
