Hmm... Are you using a language other than English as your main language in Windows? Also, did you install everything that came with the game installation? After the game installs, it automatically attempts to install the Mideo video codec, along with the OGG audio codec. If you don't install these, the game won't work.
If none of these are the issue, then would you consider e-mailing me your system specs so that I can look into this issue further? Thanks, and sorry for the trouble!
