Hi,
1.) By testing org-mode release_8.3.4.zip from ( http://orgmode.org/cgit.cgi/org-mode.git/) without compile it in emacs 25.1.50.1 an error is shown
when typing M-RET to add a new heading/item (see attached backtrace).
I am using the minimal configuration suggested in the manual.
---------------------------------------------------------------------------------------------------------;; init.el----------------------------------------------------------------------------------------------------------(use-package org-mode  :load-path "~/.emacs.d/user/site-lisp/org-mode"  :init  (load-file "~/.emacs.d/user/lisp/init-org-minimal.el")  )----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------;;; init-org-minimal.el --- org-mode minimal configuration 
------------------------------------------------------------------------------------------------------------;;; Minimal setup to load latest 'org-mode';; activate debugging(setq debug-on-error t      debug-on-signal nil      debug-on-quit nil);; add latest org-mode to load path(add-to-list 'load-path "~/.emacs.d/user/site-lisp/org-mode/lisp")(add-to-list 'load-path "~/.emacs.d/user/site-lisp/org-mode/contrib/lisp" t);;(org-capture)
(provide 'init-org-minimal);;; init-org-minimal.el ends here---------------------------------------------------------------------------------------------------------------
2) If I use the option reload Org uncompiled there is no problem when using M-RET but the following message appears:Successfully reloaded OrgOrg-mode version 8.2.10 (release_8.2.10 @ mixed installation! c:/emacs/emacs-25.1.50/share/emacs/25.1.50/lisp/org/ and c:/home/.emacs.d/user/site-lisp/org-mode/lisp/)
3) Now I force emacs to search the new org-mode version by adding a org__ to the original installation. The following message appears:File error: Cannot open load file, No such file or directory, org-table


Questions: - How can isolate the new org version from the default installed?- How can I solve this issue? 

I appreciate your help,regards,
Levis
