There are two ways to solve the not responding problem at the time of begin battle loading :
*I suggest to use the second way, because the second way is more effective
1. The First Way :
Before starting the game, first open the Task Manager (right-click the taskbar, select Task Manager), select Details, then locate Launcer.exe (the Lubu DW8 icon), right click select set priority and select High.
2. The Second Way :
Before starting the game, right-click the DW8 Shortcut or Launcher, select Properties, select Compatibility, check the “Run this program in compatibility mode for” check box, select Windows 98 / Windows Me.
