Error when trying to login in Facebook

Hi!

I'm using Xiialive Pro, downloaded from Amazon Apps, and I can't login in my Facebook account in order to post what I'm listening to.

After pressing "Accept" button in pop-up that is shown, nothing happens, and a text tell me that there was an error, and that I try it again in a few minutes.

I have been reading, and maybe problem is that Amazon's version of Xiialive Pro has a different key hash that Play Store's one. Here I'm leaving two links, with more information:

Thank you for your attention.
