Splinter Cell

NOTE: This is not the same issue that was posted in an earlier Chaos Theory thread. I am really new to Windows7, but here is my problem.

I just downloaded and paid for a digital copy of Splinter Cell Chaos Theory off of Gamestop. Simple enough; went online, spent 9 dollars, downloading no problem. I downloaded the Windows Installer Package. Upon the end of this install it brings me to another installer. This is the big file actually being transferred (around 3.3GB). That works fine. I then get to the final installer which is a Wizard. It begins to install and then I get an error while it is trying to install one of the in-game sounds. I have the option to Abort, Retry, or Ignore. I did retry to no avail, and then ignore. The installation proceeds, and at the very end I get this error message describing a list of all of the errors which are completely sound-based. This then pops up with a Windows 7 message saying fatal error, and the installer quits.

Hope that was descriptive enough. Any ideas. Please, I bought this because I am a fan of the series and this wasn't the start I was looking for. Help!

The medium from which you are running the setup may be corrupted;contact your software vendor.

Sounds to me like there is a problem with the initial download. You may want to contact Gamestop about this as it seems something didn't get downloaded or is missing.
