This is most certainly not an *easy* hack to install - it demands a bit of time, concentration and following details in the instructions very accurately.
But I can guarantee that doing that will always result the same: the hack works.
It's one thing finding a bug in a hack and then fixing it. But what you are describing can ONLY come from an error in the installation.
If you want, send me all the necessary files and templates (placed in a templatename.txt file) and I will find your error. But do that only after you checked EACH AND EVERY SINGLE DOT IN THE INSTRUCTIONS WAS FOLLOWED BY YOU.
