I´ve just dowloaded a boots file, from the fifaonline dowloads page, I read the text file and it says to install in the data\players\textures in the FIFA99 original directory, that the CD Drive. When I try to copy to it, it always says that either the disc is protected against copy files or it it is full. Can someone help me out with this? Thanks

Firstly: You must have the full data-directory on your hd (in your FIFA99-directory). If you don't have it, copy the directory from your FIFA-CD into your FIFA-Directory on your harddisk.
Then unzip your downloaded boots to:
FIFA99\data\player\textures (on your HARDDISK!!!).
