With geth having so many issues lately we have decided to switch to ethcore.io parity client.
This change will be incorporated with a migration wizard as part of the 2.0.0 Etherwall release.
The main issue blocking us from releasing 2.0.0 right now is the parity account import bug.
2.0.0 will be released as soon as ethcore team fixes this issue.
If you want to try running Etherwall with parity right now, you need to follow the steps from our FAQ page.
