Doom 3 Installation problems

[HarlemNightz27]

Im having a difficult time trying to install Doom 3 which has never happened before. When you put in the first disc it takes longer than usually to install but it goes through. while the bar fills it will still say "C:\Program Files\Doom 3\
base\pak002.pk4" then after a while an error message will say "Error 1305. Error reading from file D:\setup\Data\base\pak002.pk4. Verify that the file exists and that you can acess it. Retry or Cancel" I checked the disc in my computer and saw it in base in the setup folder. Tonight has been the very first that this has happen. What can I do to make sure I ca get a proper intallation?
