thats work for me...

Grettings..

** in a desperate tone**

BUMP! we need an answer so we can even get onto NF !!!!!!!!!!!!!!!

!!!!!!!!!!!!!!!!!! H E L P !!!!!!!!!!!!!!!!!!!!!!!!!!

im also having this problem. Havent played NF for 2 days now, and test server has
been doing this since a month ago.

Stormvanger, i tried the stuff on the forum, manual patch, reinstall whole game from
fresh download, restart, continuous tries to get in for about an hour, none of it works.
same thing every time. just says "navyfield.exe has stopped working. Windows is
checking for a solution to the problem."

EDIT: this is probably a useless bit of info, but heres a screen.

Have you guys tried downloading and installing the manual patch?

mine does the exact same thing. Open the EFNUSUPDATER then opens the hackshield and
switches to a black screen. After that the PC says NF says the program has stopped
working, and it does this everytime. To boot I cant even send in a support ticket.
Everytime I try to do that it says 404 BAD REPORT.

Maybe the HS (hack-shield) detect any program same like at Hax.. so NF never open, take
few secs, and block-Close the rest of programs, Anti-virus / Spywares too....

if not luck whit that, Right click in NF icon Launcher, and run at Admin..

again, donkunusa was probably right.
However, I was able to run everything smoothly today. Seems like time warner cable took
off the restriction.

robb, your problem probably just needs a re-install, its not the connection problem some
of us had been having

Same here, just a black screen. Can upload enfus with new patches, get to hackshield then
just a black screen. Kinda over NF. Started in 2003 Beta.. Im lucky if i try to play a few
times every couple of months now.

i do not know what can i do fix it
just i telling u why u can not access navyfield game

ps)i am sorry~~~~~ my english is NOT so GOOD!!!

I now have the same problem. I simply re-started my machine and did a virus scan, and
voila! Navy Failed no longer works. I get the ENFUNS updater opening. Click play, see
the HackShield thing pop up. Then it either all disappears and nothing happens, or I get
a totally black screen.

I deleted the game and folders. I checked the registry. I re-downloaded and re-installed
it. I even tried installing it in the x86 programs folder. Tried all the compatibility
modes, checked/unchecked run as admin. No luck.

If you have to be a computer haxxor to make the game work, most people will probably just
quit playing. Put me in that category. I just want to get on and play, not spend several
days trying to make this junk simply load and work.
