Addon Error From Ts2017 To Ts2018

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.
Following the error that i got any time that I try to play them.
One of them for example is hamburg to hannover

Thanks

 

have you tried reinstalling the addons AFTER updating the core software? A lot of things probably get overwritten by an update, indeed some get overwritten by a simple validation

 

Im trying to create a package for them, then I will unpack them in ts2018

 

I tried to unpack them into TS2018 folder but I got the same error.
How I can try to reinstall the addon after updated the core? Are there some utility ?

 

same as you did the first time round. Are the addons all third party?
