I dont know if you tried this, but try downloading this version of the game. http://download.cnet.com/Navy-Field-Resurrection-of-the-Steel-Fleet/3000-7540_4-10329493.html. That is what I did, and my game started to work. If it says an error code then download the patch, and it will work. After two weeks of support ticket with the GMs my game did not work, kept getting hacking (after doing what they informed me to do, delete this, delete that) download it. I downloaded the game file 8 times it self and the patch about 15 times. Do not download the "FTP" download. Try the one I posted here, Also have you tried the support section?
Here is some links:
Hope this helps.
