Q: Logic Pro 9 Missing Aiff files

I recently moved from a 2007 Mac Mini to a 2009 Mac Mini, upgraded to Mavericks. My install of Logic 9 is missing a lot of support files. The ones I'm noticing now are Space Designer support files. Specifically, the Warped Drums settings are looking for Drum Transformer X.aif files (x standing in for several different numbers). I have redownloaded or downloaded every optional and essential install from the "Logic Pro" menu. I have searched for the missing files in spotlight. I have browsed into Library/Audio/Impulse Responses/ and have not been able to find them anywhere.

What are my options? Do I have to trash every Logic and library file and reinstall? Can I, even though this is now a legacy application (I bought it from the app store)?
