Removing all peers (blacklistend, known, active), restaring server - doesn't help.
I still have Recent blocks [1] (with genesis block in list), Orphaned blocks [2] (both with height 1), and nothing more.
Make sure you are running 'java -cp Nxt.zip Nxt' in your Nxt directory. The directory which contains assets.nxt, blocks.nxt, peers.nxt, accounts.nxt, and transactions.nxt.
