Xbox360 MW2 Map Pack Help(File Not Recognised In Game but Is on Dashbord)

[espfutbol98]

I have the file for the new Modern Warfare 2 map pack on my hard drive in the right location yet it keeps trying to get me to download it after I already have it. I have cleared the system chache and tried everything but it doesn't recognise the file in the game but it does on the Memory tab. Any ideas?

How big is the download? would you (easily) be able to download it again...sometimes things just don't make contact. I suffered a problem like this when I was trying to download the Halo Reach beta, 2nd time lucky
