Glad it worked!
...Just some added info - the Nemesis theme was last updated on August 2, 2013, so if you haven't updated your copy yet (I'm guessing the post-types-order plugin included in the theme might be causing the issue) you may want to log into your account over at themeforest and check into updating if needed.
Last changelog:
= V1.5 * 02.08.2013 =
* Fix main menu issue on Wordpress 3.6
Good luck!
