Crystal Report Fields are empty.

I have several web sites that have been working fine for several years on a windows 2003 server. I am using visual studio 2008 and the code is written in visual basic and crystal report 10. I have a new server that is running windows server 2012. I copied all the web sites from the 2003 server to the 2012 server and they all work fine except for crystal reports. All the reports on all the web sites have the same problem. All the fields in the crystal reports are empty. The reports display but the fields are empty. When I run a web site via visual studio 2008 using debug on the windows 2012 server the fields are filled with the correct data. Is there some kind of permission that needs set? Any help would be GREATLY appreciated.
