Downloading CoD WaW Map pack 2?

Ok, so i got my microsoft points and i purchased the Call of duty 5 Map pack 2 (shi no numa, banzai, etc) and i've kept pressing to download the map pack, but its been 15% for 2 weeks!! it won't even go up 1% if i leave it for 1 hour, and sometimes when i download it says "Cannot download Map Pack 2", Also, while im downloading it says "Download Stopped Map Pack 2" even if the download screen is up!

Can someone please tell me if theres a problem? or how to make the download go faster? Thanks.

Bump

Can someone please post a response?:(

only thing i can think to tell you is to delete what you have dled and try to download it again...
