This community is backwards in their thinking.
Of course, sending a raged email wasn't your smartest move, and waiting it out would've been a better solution, that doesn't mean it isn't wrong for Badspot to completely ignore you.
It may not legally and factually be his responsibility, but do we really want a community where the only active developer won't help you with the simplest of tasks? I know people who won't buy products based entirely because the customer service and support is complete stuff.
Sorry guys that I'm not gonna jump on the bandwagon, but in my views, even know the OP forgeted up, Badspot still doesn't deserve to get to completely dismiss the entire question because it's "not his responsibility".
I mean come on, he even could've responded in a nicer fashion and linked or informed of Key Recovery, there are secretaries who deal with enraged customers in helpful fashions on a daily basis. Responding with an email informing about key recovery is so simple and easy, why is there a support email if noone ever gets useful information from it? You might as well take the email off the site.
