so you are using the stand alone version of CSS form Builder?
The stand alone extensions are not compatible with DW CS6, you will need to use a previous version of Dreamweaver with the stand alone versions.
the newer supper suite extensions, Design Extender and Data Bridge (Which consolidate the stand alone extension into 2 installers) are the versions compatible with CS6. You will need to upgrade to the newer versions in order to use them in CS6, since you own the previous supper suite versions, you are eligible to upgrade to Data Bridge for $149.99 and Design Extender for $39.99. Contact the sales department if you have further questions.
