Is there a way to uninstall Blue Marble? I downloaded it installed it with the installer but now when I try intall BUG it doesn't install properly.

EDIT: My point is that I'd rather use BUG than Blue Marble.

This should probably be in the BUG forum. What errors do you get when trying to install BUG? It should work without problems with BlueMarble.

There is uninstall option in the Blue Marble installer tool.

But i can't think of any reason, why BM will make BUG not work.
