I can see that you have uploaded a new file but you uploaded the same file
as before...one with the .pdf extension added twice. Go to
http://www.bmbc-lugoffsc.org/downloads/ and look at the file you uploaded.
You have never told us how you are producing your pdf file, but I suspect
that you are adding an extension when the pdf maker already adds one. Go to
your Control Panel > Folder Options > View > Advanced Settings: uncheck
'hide extensions for known file types". Now you will see the extra
file extension you have added to the file.
I really don't fully understand why the option to see the file extensions is
turned off by default. It really makes it hard for people to manage their
files, or even tell what kind of file they are looking at without seeing the
extension.
