Brandon Hays Feb-15 2010 Why would I need to uninstall & reinstall my FireStudio drivers? I have a Red Exclamation Mark on Universal Control Icon My Universal Control crashes when I launch it My device window is not opening properly or not opening at all My Universal Control launch window displays driver version 0.0.0 Answer: There is a known issue that prevents the FireStudio family driver from properly overwriting earlier versions of its files on some systems. This can create a driver conflict that prevents the control panel from working properly. A complete manual uninstall of the driver can resolve this issue. Please note: Your FireStudio family interface should have a solid blue sync light and will be recognized within the AudioMIDI setup utility as an available audio and MIDI device if a driver conflict is the cause of the errors listed above. This FAQ will guide you through the complete uninstall process and well as downloading the latest driver from the PreSonus website and installing in on your Mac.

The following list includes every possible file that may have been installed on your Mac, depending on which driver versions you have installed.

For example, to locate the MacHD/Library/Preferences/PaeFireStudio.startup file, you will double click on MacHD and Open the Library folder. In the Library folder, you will open the Preferences folder where you will find the PaeFireStudio.startup file. This is the file you will move to the Trash.
