We are using VS2008 and CR2008in running a server 2008r2 64bit.

We have an application that will show and print crystal report. For most part it works fine. From time to time we have a few reports that will not print either from the print banner in CR or from code behind.

Clicking the print icon in CR it opens a window "Print to PDF". Clicking the Export button it returns error

"Object reference not set to an instance of an object"


Trying to print from code behind:

"myCrystalReport1.ExportToHttpResponse(ExportFormatType.PortableDocFormat, Response, True, "Project Daily Report")" it gives the same error:

"Object reference not set to an instance of an object"


Also when we try to page using the CR banner it opens a window saying:

"The Report Application Server failed"

If I open the report in CR designer and pass in parameter it prints fine.

Can someone give me a starting point, where to look and what to look for? Thank you very much.
