Hey Paul, DD is correct the full system does not include the application builder. Refer to the following link for a comparison of what the different versions include. <a href = http://www.ni.com/labview/how_to_buy.htm#compare>Compare Development Systems</a> If you have questions on the different versions or want to purchase application builder separately please feel free to call our sales department at (888) 280-7645.
Also who did you contact about getting the replacement ethernet card? If you contacted technical support and have a service request you can always call back at 1866 275 6964 and enter your service request and you'll get routed to the person who originally took your call. If you contacted sales you could call the sales number above and they could put you in touch with the sales person in your area or the person you talked to previously if you know their name. I hope this helps! Regards, Sarah Miracle National Instruments
