Protected Content add-on isn't working

Hi!

The dropdown login box that's supposed to be inserted by Protected Content Mojo is working perfectly -even though I'll have to change it's place, because right now it's under the shopping cart. The thing is, and that's absolutely odd, it only works when Protected Content Mojo is deactivated. I thought that could be a caching issue, but WP Super Cache has been deactivated since before I got Protected Content Mojo. I want to figure out what's going on with this plugin, so I can get it working the way it's supposed to. I've already contacted the plugin dev and he has no idea on what's going on, so I was hoping you guys could help.

Thanks.
