Blue Marble

Hi not sure where to post this so ill try here. Just tried to extract blue marble .zip for CIV 4 and it gives me this error when extracting.

"Extracting to "c:\unzipped\CivBlueMarble[1]\"
Use Path: yes Overlay Files: no
Extracting CivBlueMarble.exe
bad CRC 64b59302 (should be a61015e8)"

Any suggestions/ ideas? thanks.

You might be better off asking in the creation and customization forum about problems with mods.
