manipulator tool greyed out
 

Please tell me there is a way to fix this problem. I am freaking out. I cant move my model. The manipulator is grayed out. What the heck?

You probably locked the translation channel. Select the model and go to window>General Editors>Channel Control. Proceed to the Locked tab and select the XYZ translations on the left hand side and press the "move>>" button, to move them to the Non-locked window. THis should do it!

if that doesnt work set your 3D settings to 'quality' not, 'let the application decide.'

same thing happened to me.., maya 2008, nvidea 8500 GT.
