Every time I try to open the Audio Manager of WinDVD Creator, the whole program is shutting down. It wasn't like this before.
P.S: I have InterVideo MediaOne and Pinnacle Studio II installed in my Computer.
Try uninstalling the application and then installing it again. This should fix it. Alternatively, make sure to install necessary requirements regarding NET Framework or visual runtimes and the application will work as it should. The shutdown is usually caused by the bugs or compatibility issues between various components. Repair option from the uninstaller application usually fixes most of the known problems.
