Do you have a sample file we can take a look at?
Remember that in a ELVIS Schematic you have to connect power supply and ground pins... if you look at the schematic (not the 3D breadboard) to the lower left corner you will see a connector that says GND and +5V (among other ones), if you have those connected in the schematic... when you transfer to 3D breadboard you need to connect those pins to your circuit as well. I'm pretty sure this is what's missing.
If not, then attach a zip file with your circuit file.
