Hello guys i'm again,well i've posted my error before but nobody can solve and now i solved(Dammit it's too hard but here we go) and now i'm sharing my Solution
Error:
After GameGuard verification,the game don't display nothing(black screen too),and if you go to taskmanager and kill the process,the windows gona show a message "Critical error in Windows,save your work and your pc will be reboot"

Solution:
How i say before GAMEGUARD,you need uninstall manually the GameGuard from your Computer(PS: this is not a Method from this forum)
Why Manually?
A:because when u execute a uninstall he only delete your own registry entrance and folder,and the GameGuard stay in PC
go to
Start->run type "regedit"
go to "HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Se rvices\\" delete "NPPTNT2",and after go to
"HKEY_CURRENT_USER\\SOFTWARE\\INCAInternet" and delete this registry too

Now you need acess "C:\Windows\System32" find this 2 DLL's and DELETE:
npptnt2.sys

nppt9x.vxd
PS:They are hidden,turn On to see folder and files Hidden

after all you gonna Uninstall the DBO and Install Again

Again sorry for my english i try do my best to you understand ^^'
Bye guys see you there

PS Again: I've tested this in DBO TW,i don't know if works in HK or KR

I can't find "NPPTNT2", Is it under Services once you click on it? Because that's where I looked and I couldn't find it any where.

yes,well, you can ignore because i make a search again,and see thats from another game, thank's to reminder ^^'

Oh right should I do everything else though?

yes! =D

should i stop gameguard from reinstalling when i click start? cause thats what i did and it restatred right after

well,follow this steps and you got the game working sorry for let you wait
