If you can't pay DLC content anymore and are premium, don't shit yourself.
Step 1) Go to the Playstation store (Not the one within MW3.)
Step 2) Search Vortex and there should be several of them about 3 from the top.
Step 3) Download just the regular one, with no BLES and no continent Initials.
Step 4) Download the one for your BLES and continent.
I hope this helped.
