Anybody else had this issue? Just did a clean install of OSx and transfered my music over. Half my songs can't play because itunes won't authorize my account. It asks me for my password and when I type it in i get "Fieldname: null.java.lang.execption" I retried numerous times and it then asked me to reset my password so I did that and it still not working. Actually I can't log in, authorize or deauthroize my own account at all becuase of that same error. I have no clue whats going on and I can't find anything on apples support site for it either.
