spectrum Ccpncourse2

I`m a newcomer to NMR and I have to learn everything (including understanding the different experimentation).
I take this opportunity to congratulate the creators of the tutorials for the backbone assignment it is great.
I`m now doing the side chain assignment (automatic assignment doesn`t work).
If I understood well the tutorial Ccpncourse2b allows it. but the path validation of the spectrum is not valid and I do not find the spectrum associated in the folder to do the tutorial.
So I downloaded the spectrum folder at the top of the list of exercises but it doesn`t work either.
Does anyone know where they are or how to find them?
Thanks in advance for the attention.
