For some reason, i bought the map pack after i bought the First Strike Maps and its not working or loading properly. First Strike packs are working but the Esclations pack is not. i think it was damage so i tryed to redownloading it (like 5 times) but still no luck.. it appears on my HDD but it doesnt say it got courrpted or damage. any way to fix this problem ? right now im redownloading it through this site.
