Thanks Liosha I will try mkgmap. Why am I getting an empty file? Looks like lots of errors when I run the managemaps.bat. I put all the files in the mapmanager dir and entered my map name and pasted in the url. I installed Perl with the packages and .Net4 but not playing ball. I will keep trying for a bit as I do not like to be beaten! Thanks for your help and this useful forum.
Chris.
