Here is a direct link to the GameZone link... its the fastest place to DL we have found.

Go there, find the Download Now text, then find the word "Patch" under that. Click the link Patch and download the download manager. It's quick, then find that file on your PC (wherever you DLd it too) and click that link... wait about 10 mins and you will have ALL the new maps
