Content manager closing when opening a race in Career Mode

[Alexandre Rain]

I'm having problems loading the Career mode pleo Content Manager in the intermediate Series 1 race, every time I try to open the game it closes the Content Manager and when I try to open Assetto Corsa through Steam it starts to load and a message appears error type "ERRORS With Content: highforce, highforce, highforce, highforce, highforce, union_island. view log for details." I reinstalled the Union_Island MOD and it didn't fix it, what could be happening? Someone help me?
