my friend had the same problem.
just go to Options, click on Settings. A box will pop up and there willl be two columns. Look at the right column. There should be three settings with a box and check. MAKE SURE that all three are checked, especially the one that says putting it in transparent mode. click on OK and you should be able to see yourself in the Dome. otherwise, all you will see are clouds and a tiny black dot (which is about one pixel big), which is Crono.
