 * Thanks for following up. I have just tried to use the form but I have waited 
   15 minutes and it still says it’s sending, the little loading circle next to 
   the send button is turning but isn’t doing anything.
 * I cancelled it and tried again and the same issue is happening.
 * Do you have an email address I can send the info to?
 * Thanks again.

 * I got it to work. I had saved the error log and system info as a .html file as
   that was the default but I guess the form doesn’t like that so I copied and pasted
   the contents to text files and that worked.
 * Thanks
