hello
plz help me i can open the dbo launcher but when i click start nothing happens anyone know what to do?

Open it as administrator.(the launcher).

It happened with me too! but i opened the dbo.exe(i think this is the name) it opens the game guard without opening the laucher but the game won't open but it update the game guard,next thing i did was install the patcher and i opened it as administrator(the launcher shortcut) and it worked! sorry for the poor english xP
