Backed at 50$ tier. no Carmageddon TDR 2000. tried restarting steam. and ive tried resending my humble bundle keys 2 times. No luck.
That's because the Steam is taking a while to send the gift to everyone. It's started appearing in some people's gift inventories now, so it will appear in yours when Steam gets around to pushing it your account, there's nothing anyone can do to speed it up. It's nothing to do with the humble bundle gift keys, it's all automatic on Steam.
and this link you guys at stainless keep posting http://support.humblebundle.com/customer/portal/articles/243191-humble-bundle-key-resender It doesnt work :P
The page you were looking for doesn't exist.
Stainless don't keep posting that link, I posted it to be helpful and other people have also posted it. It was the valid link to the Humble Bundle key resender back when this thread was created, but it seems Humble have changed their site around some point in the last few months. I've now updated the first post to the new URL (https://www.humblebundle.com/resender), though realistically everyone should have their keys by now so this thread has pretty much run it's course.
