FullAdder.hdl chip loaded, but something's wrong with the hardware simulator.

[Vijay99]

When I load the FullAdder.hdl in the Hardware Simulator, the HDL box stays blank. I can also load the script but cannot run it. I faced no such problem while creating Project01 and the HalfAdder. 

  FullAdder was created using two HalfAdders.

Can't really tell much without seeing your .hdl file.

Go ahead and post it -- we can delete it later.
