Can't login to admin

I love this plugin but I see that it is only updated through wordpress 3.4.2. I am using 3.5.1 and have am having a couple big issues. First of all I can no longer log into my admin for my site as of my update to 3.5.1 and before that I could not update the image for the header or even change the color. Just wondering when you will have time to update this plugin and bring it current to the new wordpress version.

Thanks and I will be anxiously waiting.
