Seems like this module does not play well with others

Below are the 'recoverable fatal errors' that are going on with this module when I use the CCK and Form Builder, just when editing a new content type. It seems like it does not get along with other standard modules. Could you please review the code for the modules being listed.

Thanks
Will
