Many rosters not showing up

I downloaded all eleven parts of the 2k14 mod for my steam game and I have all of the draft classes up to 2015 as well as all of the roster classes up to 2013 but I am missing the Ultimate base Roster and many other rosters. Is there anyway I could fix this or someone help me find out how to get the ultimate base roster on the load list. I also have the starting loading screen where it shows the ultimate base roster logo instead of lebron's face, etc. but it still won't show up. Any solutions?

Where did you put the save files of the roster?

I put all of the save files in a separate folder on my desktop and all are separated by each part.

You're doing it wrong.

Put all the saves files in your nba 2k14 folder.

%appdata%/Roaming/2k Sports/NBA 2K14/Saves

Awesome, it worked, thank you so much!
