PDF Document viewer not working in Mx7.7.1???

Hello, I have developed an application which has several PDF documents created as invoices and reports. The project was created in Mx 6.10 and the document viewer worked fine in that version, but since converting to 7.7.1 whenever you view the document it simply displays a message : invalid PDF structure. And sometimes displays an error saying to contact the system adminstrator. When run locally I checked the console for any errors, but there is no error there also. Does anyone know what causes this? or does the widget not work in 7.7.1 perhaps? Please Help

This widget works fine for me in 7.7.1.  Have you upgraded to the latest version of the widget from the app store?
