^^Good job daverave.

mtcgs: A simple, yet effective way to solve most issues/bugs in Maya is to delete the prefs folder in the main directory. It looks like Maya isn't seeing any UI elements so something may have corrupted along the way.

To delete the prefs folder, go to C:/Users/ [Your User Name]/My Documents/Maya/[version #]

Inside there is a folder called prefs. Select it and delete it, then restart Maya. It should ask if you want to copy old preferences or create new ones. Create new ones. Maya will create a new prefs folder with default settings for everything.

Of course, if you have any custom shelves or icons or whatever, you'll need to back them up first before deleting the prefs folder. Simply copy the prefs folder to another location. Then, after doing the above delete, replace whatever you had customized by copying the appropriate folders from the original prefs folder over to the new one after restarting Maya.

Give it a try, let is know if that worked.
