Muchísimas gracias! Lo descargué y funciona perfecto!!!! It got stuck due to a missing video playback module. Inside the DDR A folder there's another folder named "com". You'll find two dlls used for video playback in DDR A, which is k-clvsd.dll and xactengine2_10.dll. Open Command Prompt with administrator, go to the "com" folder, and then do this: "regsvr32 k-clvsd.dll regsvr32 xactengine2_10.dll" The video playback should then work properly in DDR A and you would not get stuck again.
