Can you confirm the wallet version in the About section of the wallet and paste it here?

Also, the dev made a mistake int he OP with the nodes. There has to be an "addnode=" before each of the IPs listed. When he updated the OP IP list, he also by accident deleted the main IP which is 52.24.99.63. In addition, the main p2p port for the coin is 11621 but you don't really have to worry about that. rpcport can also be whatever you choose it to be, preferably 10000+ to make sure t does not conflict with anything.

Make sure therefore that the node IPs are added properly in the format addnode=52.24.99.63 and add this one as well. Then try again.
