Cant Buy Pyxel Edit

I was trying to buy Pyxel Edit through amazon, but I had an issue with my account on amazon and had to back out of the payment system a few times so I could fix it. Except now, it wont let me buy the program at all, saying that I have made too many requests in a short period of time. The last time I tried it was yesterday, so I don't know if I have to wait longer or what. Is there a way I can be removed from that list or something? I am really interested in this program and its a little irritating not being able to buy it.

The last time I tried buying it was around noon today (Mountain time), so about four or five hours ago. Before that, I tried to purchase it last night at around four or five maybe. I'll try waiting a full day though before I try it again, thanks for the help!
