VST System Driver selection

Under device setup/VST Audio System. When trying to select an ASIO driver, my only choice is “no Driver”. This is a new issue as up to this point I always had a few ASIO driver selections under this drop down box. What can I do to fix this?

For the ones that come with Cubase, you may have to re-install Cubase to get them back. You could try looking in the ASIO folder and see if they are there (or searching for them as they may have somehow been moved?) For another (such as an audio interface specific driver) you will probably have to re-install that driver software. Not sure why they would not be appearing other than getting deleted or moved (the .dll files, that is). You could also try temporarily hiding the preferences folder to see if that helps. If it does, deleting them may be the solution.
