Yes, they say at they're incompatible. Error idk rlly. It might be my TRS19 SP5, I don't have platinum edition or trainz plus... Is there any archive file or anything?
Make sure you have updated the assets.
In Content Manager:
Where it says Installed, click on the small arrow to the left to expand the field.
Click on the Plus (+) on the right.
Click on the window and change that to Out of date.
On the window on the right, select true.
Click + again.
Change that to Packaged.
On the window on the right, select true.
This will show any packaged assets that have updates.
Right-click on the non-Train and non-route assets.
Choose List asset versions.
A new window will open up.
If there's anything to update, highlight it.
Right-click and choose download.
This will download updates.
I recommend saving this filter so you can do this again frequently.
If you change payware to false, you'll see any assets you installed from the DLS that have updates. We recommend checking daily. For non-DLC assets, you can easily download the updates by right-clicking on them and then choosing download.
