This is the latest version of the wallet - https://docs.google.com/file/d/0B22_jNX9iZCsTFFnN3VneDQzaDg/edit?pli=1 -

It has new checkpoints, and syncs well. Delete everything from the appdata/roaming/Emerald folder except the wallet.dat file before you start up. Give it a couple of minutes and it should start to sync. The block chain is large (the coin is over a year old with 20 second blocks), so it will take some time to download the complete block chain.

If that doesn't work, I'll check my emerald wallet for some working nodes you can add. Its on another PC at my office and I'm still at home, right now.
