Content Wont Work

[bearfay]

Okay so I only had the base game installed yesterday, and i had added a couple of hair content to my game.

This morning i installed my Late Night expansion, and now for some reason the content i had installed earlier, says that there is some problem and cannot be installed in the game.  I am really confused as to why my content was fine and in my game this morning, but now it is in my downlads folder with a yellow '!', saying that i cannot instal it?
