Open the Universal Control Application, go to Settings>Update Firmware...
If you get a pop up telling you the firmware is up to date, click Update Anyway.
If the problem persists, we can try the following:
* Power off the Studio 192
* Whilst holding down the 'Talk' and 'Mono' buttons power on the Studio 192 (this will boot the Studio 192 into Load mode)
* Open the Universal Control application and try to force the firmware update again.
Should this still not resolve the firmware issue try connecting your Studio 192 with a USB 2.0 cable.
If again, the above steps fail to get the Studio 192 to function normally, I suggest trying all mentioned troubleshooting steps on a different computer.
If the problem still has not been resolved after you have tried troubleshooting with a different computer I suggest you have the Studio 192 exchanged from where you purchased it.
If you cannot exchange, contact PreSonus Support for repairs if you are US or alternatively you can contact your local distributor for repairs internationally.
