ultimate branding plugin (my first) does not work... causes server error or just fails.

I am a customer ... a very new one... and the 1st plugin I installed did not work... ultimate branding plugin (my first) does not work... causes server error or just fails. I am using this on a single installation of WP not MU... I read that this was ok in one of your forum chats... it is the reason for my signing up. Thanks
