I have to apologize you, but our old site has been hacked recently, so we had to restore the other version, that was a development sketch of the new site. Now we're working on the brand new version, but our time resources are limited.
Things has changed a lot with import module. We had company & contact import module that was able to import contacts and companies only. Some time ago, we had rewritten this module to allow import data into any recordset (records). It's advanced module and we decided to charge a little fee for that to cover at least partially the cost of development.
The overview of the new version of Import data module is available here: https://www.youtube.com/watch?v=MXzxWy9mzwM
