I found the same error (v.13) but also a workaround. Loading TVQS from the site or from a logo link gives you a version that generates the error on exit. However if you create a custom download of TVQS (even with free account) you get a custom link. The custom link is to a web page that downloads a slightly different version of TVQS. The download page also has a "Try again" link. I took the direct URL to the file from the "try again" and placed it as the download link on my logo button. You just need to keep the logo image link as is. The result is a perfect download logo link that gets a file with no exit issues.
