Adobe 10.1 Signature Field not working

When I click on the Signature Field created with LiveCyle in Adobe X, the epad isn't activated for signature.  I get the error message below. Working with IntegriSign Epad Link to resolve but have ran out of solutions.

Error Message:  This plug-in is intended for validating signatures signed using earlier versions of Acrobat.  To sign using this version of Acrobat, use "IntegriSign for Acrobat 9.0 and later" handler.

What else can we check? 

Thanks
