Great! Thank you!It seems that I have copies of the two files that were made available through dropbox in post 26 of this thread, although I have no idea who the author was as there is very little supporting documentation in only one of the files, and none in the other. The main file is 172 MB so I do not think that sending it by email would be practical, but I may be able to upload the files to dropbox and post a link here at the weekend. If so, I will post the two links here at that time,
