You came across a little needy. Plus you gave the impression you had alot of free time or were willing to drop prior commitments if she said she was free (DLV).
You shouldn't really ask her for a drink. Tell her you are doing x, and she should come along etc...
So alter your approach to setting up a day 2, theres loads of material here (use search) and DHV (play it very cool and give the impression of a busy and exciting social calendar!). Asking out for a drink / meal puts her in an awkward position where she thinks you are expecting more and she won't be relaxed or include to accept the offer.
Cut this HB loose, unless she initiates conversation.

- don't be too nice in trying to meet up with her. If she doesn't want to see you again, its her loss and she is the one missing out! You have tonnes of other HB's waiting...Good luck.
