About all I can do is give you a link. You might look it over but it is fairly technical. But parts of it may be useful such as where log files may be located which could show what went wrong. It does have a small how to for checking the logs but that would be up to you.
Since some log files may contain personal info, it is not advisable to give others access unless you scrub the files first. If you are willing to do that you might put them on OneDrive and give us a link.
