PDX2707EU Error - Game won't start

[kasmir516]

After installing from the CD and installing the update from the web, we can't get the game to start. We get the error 'PDX2707EU - Insert original disk'. So we put in the program CD, the DVD drive takes a long time to read the disk and the error is "Unable to authenticate the original disk within the time limit." Then eventually the Program Setup Wizard pops up (although it's already installed).

We have a Dell Inspiron E1505 laptop w/ Intel Core Duo processors (1.66 GHz) and 2 GB of RAM, running Windows XP. We've check a few threads about this issue, have tried changing the date/time (to GMT), uninstalling and installing again, but no luck. HELP!!
