Well, when almost finishing this tutorial:

http://msdn.microsoft.com/en-us/library/ff677562.aspx

I found a problem on connecting the Add-in to the database, and so the lobInstance can´t be opened: http://i.stack.imgur.com/AFzie.png

This is the error code. (in fact the error message was being popped out when the Excel 2010 client starts, but I commented the exception in order to see the full details of the problem).

Microsoft.BusinessData.Runtime.CannotConnectException was unhandled by user code
  Message=Cannot connect to the LobSystem (External System).

Any idea why is this happening? I already gave permissions to the users to access the external content types, opened up the ports (1433), SQL Server 2008 allows remote access as well...

Hugs, and thanks for your attention,
