it should be a process on TASKMGR.
does your gameguard updates till the end?

For those who click on the START button on the DBO laucher and after they get this message -Game inicialize failed- or something like that, just restart your computer.

I tried everything that was said, but I didn't fix the error.Plz ppl help!

mine was working up until now don't no why because i was playing then it disconnected me and when ever i try and start the client some times it doesn't open and then when it does it says GAME INITIALIZE FAILED...................

YAY!!! i fixed it. I uninstalled then patched and reinstalled.

I've reinstalled the game but still "Game Initialize Failed".
