Deleting missing dependencies payware assets.

I downloaded some assets via the "Asset download window" that pops up when you load Trainz 2019. All I got was a load of red highlighted assets with "Installed Missing dependencies Payware". I tried to delete them but couldn't. Can someone tell me how I can delete them or better still how do I go about finding the missing dependencies? Many thanks in anticipation. Norm.

Hi Normanswick
In this case you will need to re-install the DLC pack using the information found here: http://online.ts2009.com/mediaWiki/index.php/Help:In-game_Downloading#Reinstalling_DLC

When you install the DLC packs again, please ensure that all parts of each DLC pack are fully installed otherwise the DLC pack may show missing dependencies.
