The error conataining the dsound.dll is referring to a part of the Direct Sound, that is used in the programs. This is included in DirectX 9.0. Please make sure that you update your DirectX from http://www.microsoft.com/downloads/d...DisplayLang=en

You can also do this from the Windows Update on the Start Menu.

I am running direct x 9.0c. I ran the direct x diagnostics and everything checks out OK. I removed the Indigo-DJ sound card from my dell laptop and now microstudio works OK. I reinserted the card with the program running and now the Indigo card will work. If I close out Microstudio with the Indigo sound card installed and then open it again, the program freezes and shows this error message. Any ideas why it will not work with this sound card but hoster will?
