Trainz 2009 missing dependencies

I still have the free version of Trainz 2009 I downloaded from 2018, and after I tried to download a Shinkansen that could be compatible with games early as Trainz 2006, I deleted it after it was having trouble downloading and now the "electric" sound file is faulty. As a result, all electric engines/maglev engines using the "electric" sound are unusable. Does anyone know how to fix this?

Delete the faulty version. It is likely obsoleting the good one.

I did, and then redownloaded it from the download station. Gave me an unknown content error.

Got it!

Nevermind, it's back up and running.
