Metal Gear Solid Backup question

[Jer]

When I try to backup or copy Metal Gear Solid to my computer, I get an error saying "Cannot copy Zmovie.str, cannot read from source file or disk." How can i fix this? is there something i can download to replace it, like a fixed Zmovie.str? Please help! I think it might be the protection because it is on disc 2 as well.
