An Answer

http://harrypotter.wikia.com/wiki/Elder_Wand
This site said that the core of the elder wand was made from the tail hair of a thestral.  This makes using the wand tricky - only someone who is able to accept death can use it!  So since Voldemort didn't want to die, he could not use the elder wand.
