The wallet will always say out of sync the first time you open it, as it has to download the blockchain.
This process can take up to 4 hours or so depending on your internet speed and number of connections to our network, so please be patient.
You can put your mouse over the bars icon to see the number of connections you have and the refresh icon to check the download status of the blockchain files before the wallet fully syncs.
If you already sent NLC2 coins to the wallet before it syncs that is fine, the coins will show up in your wallet once the wallet finishes syncing.
If you get no connections to the network please ensure you have no anti virus or firewall blocking the wallet from running.
Also please ensure you are not using a VPN or Proxy as this can cause you to not get any active connections to the network.
