compatibility with other plugins an issue?

hi there

i installed this and magically expected it to appear when i logged out. I’m assuming its possible that it conflicts somehow either with my template choice (currently have gridiculous activated) or with a plugin i have installed (numerous.. been playing with several options of solving the login problem)

Any ideas what i’m doing wrong? or any incompatible add-ons i need to deactivate to see this in action?
