Ditto on the "full" version install bug. Error is:
CRC Error, cannot install the following file: x:\Program Files\Red Storm Entertainment\Ghost Recon\Mods\Frostbite\map\blue_ghost\blue_ghost.map
Let us know if we can offer further assistance.

Speaking of the castle map. Did you ever figure out what caused the skybox problem as I was having a similar problem on a map i was working on?
Still a great map though.
