I have opened a support ticket with PreSonus and am waiting to hear back from them. Could iriemorse try using the free Microsoft Windows USB Device Viewer, which I've uploaded the 32 bit (usbview86) and 64 bit (usbview64) versions to a Google Drive folder (see below) and see if your AudioBox appears in any of your USB ports? Mine does NOT, meaning that the AudioBox is receiving power from my computer, but it is not sending any data whatsoever to my computer. Usually, if a USB device was still working, but did not have a working driver on the computer, you would at least see "Unknown Device" or something indicating that the computer could at least recognize that there is a device connected to it. Anyway, could you see if your AudioBox shows up? If so, you're probably in a better situation than me, as it appears something is seriously wrong with my device (failed component(s) on the motherboard? corrupted firmware?). I'll keep you posted on my responses from PreSonus Support.
Download the .exe file and .config file corresponding to your processor/operating system type (32/86 or 64).
