Relax dude, just go with the flow, if the two of you can't managed to hold a solid conversation then it not likely your going to have much of a future together anyway. If its nerves your trying to beat, forget about a quick fix, everybody is nervous at first, but once the conversation gets going you'll be fine. If getting the conversation going presents itself as a problem on account of her being nervous as well, then I suggest you take the initiative and start asking questions about her, she'll feel more relaxed talking about herself. And if the converstation doesn't progress much further that one or two word answers, run like hell :-D
