Dynamic Document Generator Plugin issue

we have deployed the plugin to another environment, while importing we added the cdt - XslParameter to the patch, which created new version of CDT and the plugin is not working as expected. we tried to delete the cdt and redeploy the plugin but we are facing the below errors while deploying.

'Could not create types for [class com.appiancorp.ps.xmlfo.types.XslParameter]. Cause: The XSD could not be imported because it contains a(n) type with an invalid name: XslParameter^1. No types have been imported. (APNX-1-4166-003)

An Error Has Occurred

Expression evaluation error [evaluation ID = D8EHAWO8] : An error occurred while executing a save: java.util.UnknownFormatConversionException: Conversion = 'D'

In forum some suggest to change plugin Key, if someone could share some insight on how to change the plugin key or Share the updated plugin with new plugin key, that will be helpful.
