Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
before I can suggest anything, I have to know what platform you are using. Xbox, Xbox one, PS3 , PS4, PC, Steam machine?
Understood. And thank you for the clarification.
Since the map pack threw your matchmaking out of sync. lets try this. Delete ALL dlc. Then, restart the playstation.
Then, before reinstalling any dlc. Try finding a match.. Can you? If you can, try reinstalling the dlc one at a time and checking for matches after each is installed.
If you get to a point that you had matches but the next dlc broke matchmaking. You may have to run without that dlc.
Please try the above, let me know the results. And let me know if you run into any issues.

To be clear.. All you currently have is just the base game installed and no dlc or other map packs?
Understood. We may need to try something a bit more in depth.
Try option 3 on this page. http://www.wikihow.com/Reset-a-PS3
make sure to backup your saved game data first as it suggests, just in case. Then, you want to perform two steps.
restore file system
Do the first. and when it completes restart the ps3 and t hen check AW matchmaking. If the problem is still there.
Go back and choose rebuild database, then test. Let me know the results, or if you run into any issues completing these steps
