Need some help...can't get original bkbrds back

So like a fool I did not do a bkup and am not running a mod tool. I have several folders all of which my idiot brother pasted all the contents from the dc/marvel mod into. Now I have a problem where my Olympic court on my ubr roster has Marvel backboards and signs and whatnot at the top of the stadium...i also get these when i create a team...the whole new stadium is my team colors except the dc/marvel logo in middle, bkbrds, and the signs up top...anyone know if there is a way to only replace the files that the marvel/dc release would have messed up? any help is greatly appreciated...just something unsettling about playing on the olympic court w/ dream team vs. this year's squad w/ marvel/dc bkboard

Never mind. Did a clean install to save the hassle.
