It sounds like you have not selected all the components that assemble a car. On the main page the name of all the components that make up the currently selected car are displayed,Chassis TC4, Battery Lipo1S2P and so on. If there is no name shown then open the "Car Manager" select them from the drop down boxes and then click save.
If that isn't the problem then please provide some more details on which chassis you are working with. Or even better From the "Car Manager" export the file and email it to me so I can have a look.
