You can fix the issue by running the PublishReports.exe tool from the Tools
directory of your install location. Example: C:\Program Files\Microsoft
Dynamics CRM\Tools\PublishReports.exe
The executable takes a single parameter: the unique name (as specified at
setup-time) of your organization.
This tool will recreate any CRM-related items on the report server, so
everything should work as expected after running the tool and perfoming an
iisreset on your CRM server.
