Cod5 Zombie Maps Problem

Okay. I updated to 1.5.
I open up Cod5
I go to solo to play the new zombie maps
And theres just the original cod5 zombie map (something undertoten)
I have finished the solo missions.
Do i have to do something to unlock the maps? or should they appear automatically and its just my cod5 program having problems?

Thanks for your responses

And please don't go like 'sukz for u lolz lolz o brb going to chucky cheeses'

Only helpful comments please!
