Hello. How do I retrieve a lost ap file from Steam? The CSX SD45 Pack.

Hi, this should work:
-- Open the Steam DLC manager for TSC, which you can find on the right side of the screen if you scroll down a bit on TSC's library page
-- Disable the DLC in question and wait for Steam to finish a tiny update for TSC
-- Enable the DLC again and Steam should start downloading a fresh copy of it.

Cheers,
MIchael
