Problem with skin ._.

[oOGretuxOo]

Hey everyone =) . How's doin'? Anyway.... Today I've finally loaded for first time Hexxit modpack (why? because on older version of Techinc Launcher I couldn't get any modpacks) and I instantly ran into a problem. The problem is, that in game  I see my skin as Steve's skin (default skin), but not my skin. My PC is connected to internet, I have bought minecraft account. So I don't really know how to solve this problem . If someone knows how to fix this problem, please tell me ok? It will be BIG THANKS.
