Kodi 17 Crashes and Has Lost Sound W8.1

I’m new to Kodi and so far it’s been mostly frustration. I download V17 and it worked OK for awhile although was not able to get the surround sound to work; just the front speakers. Was advised to go to log file and install debug haven’t been able to do so because the steps don’t work with what shows on my system which I described in detail on another post.

And now I can only play Kodi once and have to reboot the PC to get it to open again after closing it and now the sound has stopped working completely. Is there a way to reset to certain default settings? I can’t troubleshoot with debug for the reason mentioned previously. I hate to have to uninstall it completely and lose all of the work I’ve put into setting it up.

I could really use some help because I can’t use Kodi at all now and it’s supposed to be my mane source of TV viewing now that I’ve cut the cord. A friend bought a Kodi box for $260 and I teased him for spending that much on something that is essentially free, but I have to say, his works perfectly every time.
