How can I fix my Authentication connection problem? sometimes I get Game Intialize Failed, or when I finally get the game runing at login screen, the "START" button doesn't respond... after about 100 times I get in if I'm luky :( . The game was just fine few days ago.

Try to launch game by DBO.exe

No difference :/ it's all the same

Try re installing or download the latest client also install net frameworks 4 and update your bios .

I have all that... and downloading and reinsalling all over makes no difference I already tried that... sometimes the game does launch... but most of the time I get authentication failure... P.S This has happened to me in the past so I want to end it once and for all...

Are you running it as admin?

You sure your game is fully updated? (Which brings me to swordsman45's question, as you need to run the launcher in admin for it to update correctly)

Also, what Operative System are you running? (Windows XP, 7, 8, etc)

yes sword, I am running the game in admin... lol every guy nows that -.- and i my game weren't fully updated then I couldin't start my game eventually. I thought I told you I can launch the game but after like a 100times trying... the problrem is somewhere deep in my internet. my internet is working perfectly and no lag but I can't connect to taiwan servers I guess or something... maybe I need to push my internet antena a little to the right or the left? xD. P.S. as I told you before the game worked perfectly until now :(

If it used to work before and everything else is fine, I'd say it has something to do with the game itself, not your internet. But that's just my guess. Now, what exactly, I don't think we can figure it out with so little information.

Well, I think so too... but it's all there is to it so that's why I can't figure it out on my own :/
