I had trouble as well, the first time I clicked out of the "Waiting for Paypal" window after a minute and then I thought maybe I should have just waited a little more, so I paid again (so they got $10 total from me) and let it sit.... for well over 30 minutes. Eventually I gave up and grabbed a Steam key from ...another source (hey, my Paypal account says Humble Bundle got my money so I'm not pirating... also fwiw the source said they had the same issue) and used that.Sgt. Sykes said:BTW is anyone having problems with processing their orders? I've been waiting for over an hour now.
Then about an hour later I got an email thanking me for my order. Just one email though.
So I guess maybe you should give it some more time. Something seems buggered up.
