No, I haven't. Same error each time. Maybe it doesn't like yahoo addresses.
(and no, the annoying captcha was entered correctly each time).
I've got the actions now anyway, so I won't bother with their site.
From what I read from Daikon Forge recently, it seems like they're going to stop support with v1.0, and moving ahead with v2.0 which won't be backwards compatible and will require purchasing even if you've bought v1.0. I think I'll probably look to another provider, one who isn't charging twice.
