Missing Water Textures????

Hi, I've just installed FS2004 on to a new hard drive but when i create a flight i find that the water textures are missing. All the land masses are there but instead of water there is just a black void. It's like the land is a mask but there's nothing for it to sit on top of.I did have a small problem when loading fs2004, a box popped up saying that it couldn't copy a file across to the hard drive but when i selected the option to 'retry' the installation carried on as normal. I assumed that the file copied ok after that. If this could be the cause of the problem does anyone know how i can reinstall the water textures from the cd's?
