Ok I did the "ls -lt" command you told me to run in the same directory as where I ran it last time and it didn't come up with anything.
I ran it again (the installer) and then did your command and copied everything it displayed incase I did anything wrong:
nexus@Venom:~/Desktop/ATI$ sh ./ati-driver-installer-8.28.8.run
Creating directory fglrx-install
Verifying archive integrity... All good.

Sorry if it's me being stupid
EDIT- Just reading through it again it does say "Removing temporary directory: fglrx-install" so could that mean that the file you want to look at (ati-installer.sh) has been deleted?
