"Default Wagon" Dependency Broken

I was trying to download a TTX boxcar from JointedRail's site and somehow managed to break the "default wagon" dependency <kuid:-1:42004201>

So now none of the previously downloaded TTX cars are available! Can anyone tell me how to fix this? Thanks!!

Click revert to original in CMP on the dep that is broken.

That worked! Thank you!
