The new c-note client don't connect to old clients and use different blockchain.

Look at the block number of the cnote 2.1 wallet. That snapshot was taken while the wallet was still synching. Let it synch up and it will connect to old and new. I have 12 connections to the seednode and some are new and some are old.
