Projects' audio getting assigned to 'silent hardware output.' How do I reassign to UA-25ex

Hi everyone, somewhere along the line my projects started getting screwed up with my Master getting reassigned to "silent hardware output." I think that it has to do with me unplugging my UA-25ex at the wrong time (I am sharing it between two laptops that sit next to each other). But even though I can open a new project and have audio, I don't know how to (or if I can) go back to the screwed up projects and reassign the Master back to my UA-25ex. Does anyone know how to do that, or have any other feedback about why it could be happening, or any sort of other fix? Thank you!!

It is as simple as selecting your UA-25ex from the master buss's output drop down box. If it is not there as a choice you need to go to Preferences--->Audio---->Devices and make sure it is checked in that dialogue.

If it isn't present there you'll need to re-install it.

If for some reason your template has 'lost' its assignment then you'll need to do the same to the template and then re-save it.
