ARForm 10.2.200.5 Error running in Report Builder

Starting modifications on SSRS ARForm for 10.2.200.5. In both Report Builder and Visual Studio when I try to view the out of the box report Standard SSRS getting “Object reference not set to an instance of an object”. The form does Print Preview and Print okay in Epicor. Other reports view okay with same method in Report Builder and Visual Studio,

How do I find what is causing this? Anyone else have this problem? Will support help me?

When you try to open the form or when you try to preview it?

When you ran the report to get the guid did you select an archive period?

Are all subreports published on the report server and linked correctly?
Are all the subreport parameters set up correctly?
Are you passing a NULL parameter to the sub report and the receiving parameter is set to not allow nulls?

I am just trying to preview with the guid the out of the box form, no modifications. Not a copy, but the standard SSRS report and standard subreport. I tried Report Builder on the working version of the report. I did select an archive period.
