New Report not showing any results

I have a few different reports that we run for the same module. I have been asked to create a new report today however when I have created it I do not get any results when I preview the report event though I know I should have some jobs listed on the report. All other existing reports are working fine. I have run a rebuild and repair along with a repair roles and rebooted out CRM server however this has not resolved the issue has anyone come across this issue before or have any idea as to why this may be happening.
