hi guys i'm sorry but my english is quite bad . my problem is that i can only play the compain mode and the defence somethinng mode . when i chose another mode it asks me to download the pack but i can't do it what should i do ?
You need to download the DLC packs from the store. They are free and were added to all the playlists' cycle. I have bought them myself earlier but I think it's just like buying them but they don't cost anything.
Being a not too savvy computer guy the advice I could give you would be to uninstall/re-install. Keep your hopes up though because I'm sure someone will help you out.
