There is a little tutorial click here if you aren't sure how to save a log file. You may find that you can't paste the log all in one go here. That is because there is an 800 word limit to posts. So do it in two or three parts if you need to.
It would help if you could double space the log as it would make it easier to read here.
I don't need to post the log. Once I saw it I knew what to do. Just tick the boxes and delete the downloader files. I did it first thing this morming and havn't had any trouble in the last 12 hours. I've saved the programme just in case it happens again.
For now, all I can do is give you a big thank you.
