CrystalReports

I have a web app that I am working on and I deployed it to the server. When the user logs in to the web app and enter in some data into the textboxes and saves it to the database the user can also print out a Crystal Report. When the user clicks on print this error comes up:

 Error in File FormAReport {63A7C276-5058-451D-B107-409E99203136}.rpt:

On my Deve computer the web app works. The user can see and print the report. How can I fix this? What else do I need on the server?

The server I have:

Windows Server 2012 64-bit
IIS 8

I deployed the web app using Publish Method: File System

Please Help!!! Thanks!!!
