Hi there!

I had the same problem, i personally reinstalled everything and my problem was solved. I don't know if you installed any editors but ...

I think the problem lies in the editor(s). The fist time i installed both of the (mohtools and spearhead SDK) than all my skies were black. The second time i installed ONLY the Spearhead SDK and my problem is gone.

Don't know if its the problem but you might never know. If i were you i'de try to uninstall mohtools (the first radiant) and keep only the Spearhead SDK... who know? it might work.
