I am having that problem too. When I type "(" into my message box to pick an emoticon from the emoticons panel, the panel only seems to have the default emoticons on it. On both page 1 and 2 there is bath the same dafault emoticons.
well i think they should be there in cumtomize window but their colour might be white or u can say that they are invisible.... try to klik on different places in the laarge space where u can select emotion ... try this it may help u out..
