Invisible Auxiliary Tenders

Hey guys!
I've been dying to get the DSGDDR aux tenders to work.I recently downloaded the aux tender and the U.P. Mega Pack,and the original aux tender doesn't appear,nor do the re-paints.The only thing that appears is the couplers.I've read other disscusions on the forum and all of the +'s apply to me.I have the blueprints pak,and all of those thing still there,but I don't know what's wrong?
Can someone help me out?
Thanks!
