I don't know if this goes here or not, but I'm having problems with unlocking new shouts.

It will not let me unlock a new shout, even though I have the word and I have two extra souls.

I've killed 5 dragons, but I have 4 shouts and will not let me unlock the 4th shout.

Do I need to go to High Hrothgar to train or something? I've done the Horn of Jurgen Windcaller quest.

Anyone know?

same problem here,
4 dragon souls
so far i've only unlocked the first two shouts, now i have the ice one sitting there but i can't unlock it, says i need dragon souls, but says right there i have 4.

Yeah, it's really irritating and they need to patch it.
