Sorry to have to do this, but I must've backed this early on in the campaign and then, at some point, viewing this when not logged in, assumed I had not backed it and figured that I probably wouldn't now, just because of finances. I've only realised now that I HAD backed it because it's tried to take money out of an account where there isn't any. If I can cancel the pledge (it's for PDFs only, so hopefully not a massive dent on your total) that'd be great, but otherwise the money likely won't be available until pay day on Friday.
