Welcome
I guess that you are using the current version of the abracadabraTools DC plugin into your Acrobat 9.
This could raises compatibility issues because many things have changed in 10 years.
With Acrobat Pro 9 you must use abracadabraTools version 3.1
Download this PDF and open it with Acrobat Pro, the plugin and instructions are in the PDF (remove any previously installed abracadabraTools version before installing this one) : http://www.abracadabrapdf.net/download/abracadabraTOOLS_31.pdf
