Yes I have enough lindens for the purchases, I've tried buying things that cost and buying free demos but still the same problem. 

The buy now disappears after I click on it and the page doesn't go to the next one like it should after you buy something.  The buy now button turns white (disappears) after I click it and there is no other option to pay for things.

I'm talking about the final buy now after you click on check out.  I've been on SL for years I know the process of buying things on marketplace.

Yes I am logged in.  I tried logging out and back in but that didn't work.

I can't buy anything from the marketplace anymore for some reason.  It lets me put items in the cart and I can check out but when I click on buy now it disappears.
