So I tried installing my AOE3: Warchiefs CD again. It all goes good,I enter my Product Key and it statrs installing. But in the middle of my instalation proccess I get an error message saying that a certain AOE3/art4 file is missing and asks me to retry, continue, or cancel. Retry fails so I pressed continue. it keeps going but at 99% it asks me again. I try pressing retry and it says 'File not found' or some crap close to that. When I press continue I get the error message after 5 minutes again, and cancel stops the installation.
I've retried the installation several more times with no success, I even tried restarting my computer.
Any advice or help?
