Same problem as him. I edit vsync.conf file but, nothing happens "No block source available on the left" and a red cross on the right corner...
Anyone knows what to do ?
Edit : Finally install wallet on another PC, zip everything from %apdata% except wallet.dat , dezip on the same location to the PC who doesn't work.
For anyone else still having this issue, a missing step that seems to work is to delete everything except the wallet.dat and vsync.conf files in the %appdata%\vsync folder after adding the nodes to the .conf file (do this while the wallet is shut down). Good luck.
