Hello Paul,
	Here is what I've done :

	1) check you've the org-elpa repository configured :
	my package-archives has this value 
(("gnu" . "http://elpa.gnu.org/packages/")
 ("marmalade" . "http://marmalade-repo.org/packages/")
 ("melpa" . "http://melpa.milkbox.net/packages/")
 ("org-elpa" . "http://orgmode.org/elpa/"))
	2) install melpa package from melpa (special handling for the MELPA 
repository [github])
	3) exclude org from melpa by adding / customize var package-archive-
exclude-alist. Mine has this value '(("melpa" org)) this is explained on melpa home 
page in customization section (near http://melpa.milkbox.net/#installing).
	4) uninstall org-2013...
	5) exit emacs then install org-20130715 (you should only see a version 
like yyyymmdd and no longer see a version with yyyymmdd_hhmm)
	Hope this could help

	Pierre
