We've updated the messaging on our front-end, ads, and CP to reflect that we are no longer offering a free-trial but you can sign up and use promo code SSDTWEET to get a free credit so you can still test for free.
That happened to me too. I went and found a coupon code and used it with my credit card info, worked like a charm and I couldn't be happier. :)
And also.. you don't want those self disappearing trial servers anyway. ;)
You won't be notified about changes to this idea.
