The most common cause of PDF files not generating is having pop up blockers turned on within your browser.
To fix this issue, find Options or Preferences; you may use the following resources for browser-specific guidance:
Google Chrome: https://support.google.com/chrome/answer/95472?hl=en
Safari: Choose Safari > Preferences, then click Security. Uncheck the the “Block pop-up windows” box.
Also, please double check vintrace isn’t open in a second window where the PDF is just reloading behind the current window you have open.
If you are still having difficulties, please contact us and include the version of the browser you are using.
Other extensions such as Grammarly have been found to cause issues with pdf downloads also.
