UT2k4 installation problem

[pay]

Hi,
When i try to install Unreal Tournament 2004, I get this error when i put in the 3rd game disc.

daniel@ubuntu:/media$ sudo sh cdrom0/linux-installer.sh
Copying to a temporary location...
Verifying archive integrity... All good.
Uncompressing Unreal Tournament 2004 for GNU/Linux 3186......................................................................
UZ2: Failed to fully write [/usr/local/games/ut2004/Textures/SG_Giest_redset.utx]!
./setup.sh: line 148:  5514 Aborted                 "$setup" "$@"

I made a backup of the game when I bought it on a dvd with ISO images of the game discs but when I try to install the game from them it gets the same error on the second game disc. Does anyone have any ideas?
Thanks

Might be a faulty/corrupt ISO image.

If thats the case I guess I'll just download a torrent of the game and then use my serial no. that I bought. Thanks for the reply.
