Hello,

I'm afraid that in order to resolve this NF may need to be completely removed from the system. Please check your windows registry and manually remove all entries of Navyfield and SDEnternet to make sure it is fully removed before attempting to install using:

http://navyfieldusa-sdenternet.ktics.co.kr/Download/NF1326.exe

To check the registry please use the following (please be very careful as editing your registry incorrectly may cause serious damage to your Windows installation or other programs):

1. Click on Start and select “Run” (located immediately right once you click Start)
2. Type in “regedit” and press enter
3. The registry editor opens
4. Expand the branch titled “HKEY_LOCAL_MACHINE”
5. Expand the branch titled “SOFTWARE”
6. Delete any SDEnterNet or NavyField folders
7. Close the registry editor and restart your PC
8. Reinstall using the latest full client available on our homepage link.

Sorry for the frustration,

TeamNF
