she's very active on a website i moderate, which leads me to believe that, yes, she is blowing you off. i'm really sorry to hear this, since we've always had pleasant transactions in the past.

as maddogairpirate said, you did talk to her a month ago. i'd be inclined to say "give it more time", if not for the fact that she's been ignoring all attempts to contact her. she is active, and as far as i'm concerned there should be no excuse.
