portraits overwriting?

I installed the new UBR roster and the portraits overwrote a lot of my fictional draft classes which kind of ruins the purpose of association if im drafting a white guy with a picture of robert horry or something like that. Did not back up. Can this be undone?

it seems i do have a backup, but is it just the portraits.cdf file only that i need to replace?
