Run the import on the archive server not on a client computer. Also make sure the variables you want to import are "mapped" to custom properties and that they do exist on the data card for the files you are updating
This will get you started. I've recently debugged this thoroughly with solid works and have been developing an XML connector for ERP import.
I can also consult at a much more competitive rate
Hope this helps
By the way, I am unable to see the image on your post. I am doing some development tonight working late in the office for the next 3 hours so go to my site & get my contact info. I'm sure we can get you going quickly at no charge.
