I just purchased the Collection 1 Downloadable content for MW3 on PC. I purchased through steam, and I checked my bank account and the $15 was charged to my account. Steam them updated COD MW3. After updating I launched MW3 and it would not let me play on the DLC game types. When I right click on MW3 in my steam library and go to view downloadable content it says that I do not have any downloadable content. Thank you for helping me resolve this.
