unable to participate in the competition system

I can't enter the competition servers, when I click on join it gives me this error:


Cannot read property " find" of undefined

Why ?

 

Have you already signed up for the Competition Server series you tried to join? And did you download any missing content,(cars or tracks)?

 

Yes I have already signed up, I downloaded the contents from the workshop and I also entered the official servers of Studio 397. I do not understand how I miss it and not knowing the English language it becomes even more complicated

 

Se ti ricapita, fai uno screenshot della schermata e postalo. Probabilmente è una banalità.

 

The problem is this ...

 

I haven't run the Competition system for some time, so forgive me, this is more of a question to the whole group, especially experienced CS users.
It looks like he has a custom skin. Does the CS accept custom liveries?

 

No custom skin, I randomly chose one present in the mod.

 

ok, sorry about that, I did not recognize it. My fault. Still doesn't help you, I don't recall any other error messages like that.
