Addon error from TS2017 to TS2018

[germano_rm]

Good afternoon to all,
I have a lot of addons that i was using with my TS2017. I bought TS2018 but now all my addons doesn't work. The only addons that are working are the addons belong to TS2018.

What is exactly not working? Are the add ons installed, do they crash, are you sure you did not mess with the installation directory? Did you try to verify the cache? Please be far more specific in your question if you really want help.

This message says a number of vans for the Hamburg-Hanover toute are missing. Do you own this troute? You can check if the assets for this route are installed.Starting from the installation folder, follow this path:
Assets\RSC\HamburgHannover

Here you should find the file HamburgAssets.ap Probably this file is missing. If you own the DLC, try to verify the game cache and see if this helps.
