Okay here is my situation ladies and gentlemen I saw on EOFF and very well that the for an example the ultimate limit break of Tifa was Final heaven I got Final Heaven playing that at the piano in her house but there I went to itens and then I select 'Final Heaven' and she said that she wasn't sure about that but... what does this mean? She won't learn the Limit? Oha dn I also got 'Highwind' of Cid and he also said that... okay what is wrong? Not to mention 'Cosmo Memory' and 'All Creation' that doesn't work too...

What do I have to do?

Thank you... oh and one thing I have the Shinra submarine... but I have to go to a waterfall to get Vinc weapon and I can't go there coz the submarine don't let me how do I go then? Supposing that i don't have Gold neither, blue chocobos....
