I Need help!

You may have to accommodate the installation path of the game, Local disk C / DragonBallOnline / (Unzip the Rar file)

Try that the destination folder of the game does not have spaces in its path

You should also update the video drivers of your computer.

Inside the game files is a .txt file called dbolog.txt . you should clean the text file , try to open the game again and then you should show a screenshot of the error that is logged in dbolog.txt that could be a better follow up to identify the error
