There has been reports that some players are experiencing issues with our launcher.
We are very sorry about this problem. Here are solutions which has solved most of
this issues.

If your client version is above 1.303, the message 'Data file has corrupted' indicates
that one or more of your data files have been damaged.
To solve this problem, you have to re-download data files.
Please navigate to your C:\Program Files\SD EnterNET\NavyFIELD directory and
delete all files ending with .DATA

Afterward please relaunch your NF launcher.
It should attempt to re-download the missing data files.
This will save your time much than totally reinstalling the game.

However, if your cient version is lower than 1.302, or if this solution does not work
for you, you will have to reinstall the game completely.

First, please uninstall NF through Uninstaller that we provide.
Also make sure you select to remove ENFUNS Updater as it may be listed separately.

Once removed, please go into your Program Files folder and delete any SD
EnterNet or Navy Field folders manually.
Check if game, game folder, ENFUNDS updater, and NF Registry file are all deleted
properly. Open your "search or find" option on your windows and type "navyfield"
and delete all the files on there.

**If you are the Windows 7 user, make sure that your Registry files are also
removed by this step.
Once you click the little winodws menu button, you will see the "search programs or
files" box.
Please type "regedit" and find "SD Enternet" folder or any navifield game folder if you
changed the game folder name.
If any folder related navyfield is appeared, please delete it as well completely from
your hard disc.


After NF has been completely removed by following the previous steps, please
download the newest client file from our website and reinstall it. (please make sure
the version is the newest version.)

You can use the link below for the latest client file:

After this, the game should be started without any problem.
