@Crayyy Were you able to start it in the past? Maybe the program settings are broken. You can try to delete the musicmaker.ini in the directory C:\Users\YourWindowsUsername\AppData\Roaming\MAGIX\mm32 This will reset the settings. This might help.
@Crayyy What are your audio driver settings? I recommend the following in case you don't have an external USB audio interface:
Open the Music Maker program settings and go to the Audio/MIDI tab. Select the Music Maker ASIO driver. Click on the Advanced button to open the driver settings. Select your audio input and audio output and set the buffer size to something reasonable like 512 samples. If the sound stutters or you get instabilities increase the buffer size to 1024 samples or 2048 samples.
