Theme Logo Reverting to Template Logo

Hey there,

My blog is at https://theblogwriters.com. I’m using the heliumified template, and it allows you to enter a picture for a logo. I’ve added https://www.theblogwriters.com/wp-content/uploads/2012/05/BlogWritersLogo.png, but I installed a couple of plugins (made some changes to WP e-commerce and installed Google Analytics for WP, and now it keeps reverting back to the template logo.

I’m pretty new at php/css, so I’m having trouble finding what I need to do to make the logo appear. Help?

Thanks so much.
