I've been trying off and on to see her since mid-July.  Had similar experience to Fisheater and have decided, after lots of e-mail conversation/explanation, that she is basically a good egg whose been having all manner of internet, phone and car problems.  So far, we've agreed on 3 meetings; she's cancelled once, I've cancelled once, and she no-showed once.  I didn't hear from her for a few days and then got a witty e-mail explaining that her car had konked out in a remote area with no cell coverage and no pay phones.  Good luck!
