Cant find the dependency "bldgprop_vol1" anywhere. Can you be more specific than "available from Support Files". Thanks. ()what() :'(
Did you click the link to where it said Support Files (http://www.sc4devotion.com/SC4D_Maxis_files_EULA.html)?
You need to read and accept Maxis' EULA by clicking I Accept the terms --> proceed to Maxis Tools and Updates.
After that you will see four sections, the first one of which is Lot Editor.
The explanation to the right of the says "bldgprop_vol1.dat and bldgprop_vol2.dat are available in this section".
Click Lot Editor, and I'm sure you can find your way from there... ::)
