I have Microsoft windows 7 and I am annoying to utilize Ulead video studio 10 on it. The whole thing works on the program apart from the sound. If I attempt to play a video clip the sound work and if I attempt to only play a sound file on its own it only says "anonymous external error". If anybody has any way out to this trouble then please, hit me with them. I mean please provide some way which help me to come out from this problem. If possible then please also provide me some information about video studio 10.
