I have downloaded the server and client and everything from this site (by the way you guys are awsome!

) but i cannot seem to get my IP to work. I have a Dynamic IP and my internet service provider will not allow me to get a Static IP for whatever reason. I have a DynDNS account and a No-IP account but I am not sure what to do with either of them. I have all my server files just set to localhost (all the IP's are 127.0.0.1). I don't know if this is right? Or should i have those IP's set to the DynDNS ip? Currently when i change the IP in oem.dat/.ini the game says logging into server for a second then the client abruptly closes.
Please help me! I will be very grateful!
P.S. I know my DynDNS works because i am currently hosting my website with it.
