Er-...Bad insall? Reinstall?
Otherwise you're not finding servers that aren't playing them. Which really shouldn't be an issue as those three (besides Mehtro) are the most popular maps in the game in terms of server rotation.
Edit: OH and check your server filter settings before you reinstall, DICE made some server settings reset and make the last expansion ONLY maps be selected. So make sure your server filters are set to what you want.
No, it's not that. I was playing those maps without encountering any problems before I upgraded to Premium. Now when it's on the loading screen for those maps the game just...hangs.

I already tried reinstalling the game. No Dice.
