I downloaded cdlc file and unpacked it with Rocksmithtoolkit just like stellarfirefly told in he's guide.

My song (master of puppets) is in song list and i can "start" it but after tuning window game freezes.. whats the problem?

i tought the problem might be the song, but i tried others songs and same thing.

@@MOOMI well try CFSM from here for having ease of access to your cdlc and to sort them and fix plus you need Cherub Rock dlc to play cdlc without changing appid thing :)

Custom songs could do that amps screen hang if you've got same key ID on couple of them or duplicate of same file.

Duplicates are a good guess - I'd check the dlc folder and for a test you could remove all customs except one to see if it works.

 

Another thing to try - in steam for the RS game open (with right click for the context menu on the game entry in you game list) properties > local files and "verify integrity of the game files"
