Adding Text to A PDF document

My old code would print a certificate for a user once they pass a test stored in an Access Database. Once the provider upgrade to CF10 the cf_pdf changes to cfpdf and then that is where i get lost. This code no longer works and I do not know where to start to make this work. Any suggestion would be helpful. Once I change the tags to cfpdf, then I get more errors such as DDX which is new to me.

<cfif GetAuthUser() is not "">

               <cfquery datasource="GetHelpNow" name="Get">

               SELECT * FROM Users WHERE user_id = #GetAuthUser()#

               </cfquery>

               <cfif (Get.recordcount is not 0) and (Get.user_certFailures is 0) and (Get.user_certCompleted is 1)>

                              <cf_pdf file="GetHelpNow-Certificate-#GetAuthUser()#.pdf">

                                             <cf_pdf_info file="Cert.pdf">

                                             <cfloop query="request.PDFInfo">

                                                                           <cf_pdf_read file="Cert.pdf" page="1" />

                                                                           <cf_pdf_text x="360" y="396" rotate="90" align="center" font="Arial" size="20" color="000000" bold="true"><cfoutput>#Get.user_fname# #Get.user_lname#</cfoutput></cf_pdf_text>

                                                            </cf_pdf_page>

                                             </cfloop>

                              </cf_pdf>
