This package is also invalid. Same problems like on your other release (quadropolis.us/node/1580).
I tried to explain how to fix it on that node.
Some words about the skybox. I actually haven´t tested it ingame, because the package is messed up, but I had a look at the files. It seems like everything is ok, but there´s still space to improve. What about adding a moon and some clouds? It appears a little bit boring to be honest...
Keep it up and fix your packages! :)
