Problem Sign up GTE Winter Series

Hi guys, when I try to register to GTE winter series I get this error: Error setting series GTE Winter Series (400), how can I solve? Thanks

 

I forgot, I have all tracks and cars

Don't make the mistake I have. I use a custom skin and now can't race GTE at all.

 

I can do the warm up then when race starts it kicks me to pending every time.
So a few bugs to fix but that is understandable as it is in beta.
