Can't open live HTML preview

[nerdyguy1990]

Hi. I downloaded Cudatext and installed live HTML preview, and I also edited the settings so that the browser is one of my daily browsers and set it to the path where the file is. I click start server, and it loads in the browser, but it doesn't connect. I've tried changing the port number and still nothing. Every single time the browser says can't connect, and I've double checked the settings, everything seems in order. Is there a way to fix this?
