    Couldn't find this in any of the other FAQ's
    I get the following message on install Disc 1

    Feature : **IS_STRING_NOT_DEFINED**
    Component : Common Game Sound Files
    File : E:\common\data\sound.m4b
    Error : Data Error (Cyclic Redundancy Check)

    Anyone else had this and how did you get past it?
    Thanks in advance

    As a first step, take a look at IS_STRING_NOT_DEFINED solution.

    Not to be a bother...

    I'm having a very similar problem. My error is exactly the same, except it's "video_6.m4b" instead of "sound.m4b". I clicked on the link you gave them, but it just took be to the general forum site. I searched but couldn't find anything. I don't suppose you have a working link?
