Install problem

[twylo]

When I try to install HL2, on the fourth disc I get the error "Error 1305. Error reading from file C:/ProgramFiles/Valve/Steam/Steamapps/counter-strike source shared content.gcf. Verify that they exist and you can access it.

Any one know whats wrong and how to help?

Did you choose a full install with Counterstrike: Source included as well? Some people recommend that as it sometimes fixes this 4th disk bug during the installation.
