[Plugin: Multi-page Toolkit] Blank pages when activated

Hi,

This plugin would be perfect for what we need to do (paginate one-file, markdown syntax books) but unfortunately it does not work.

I tried it on a wordpress 3.05 install, with default theme, and when the plugin is activated , navigating the site gives empty pages (zero content).

Admin dashboard is fine though.

Disabling the plugin, all the pages shows up as normal.

Do you have any hints on how that could be fixed?
