If you have "The Big Bundle" you can open that and download all the games from there.
Each game download from the bundle has all the modules and updates and you just need to activate the ones you have.
If I remember correctly, for CMBN the base game is included in the download and does not need to be activated.
I needed to activate the V3.0 upgrade for CMBN and CMFI
The BF order page only shows order #'s and dates not the name or activation code for each purchase.
I created a doc with the order#, name, date and activation code that made it easy to copy and paste the activation codes.
