I saw the following error in the Tomcat log:
Stderr:
ERROR 1146 (42S02) at line 21 in file: 'D:\spectrum94\Spectrum\Install-Tools\rpmgr\sql\srmdbapi\ddl\create_v_fact_event.sql': Table 'reporting.event' doesn't exist
This indicates event table is corrupted or missing. Do you have latest mysqldump backup of your SRM database? If so you may need to restore it. If no then I guess uninstall and reinstall OneClick Server + SRM will be the fastest way to fix this issue.
It will be unfortunate if OneClick Server component is installed on the SpectroSERVER machine as the entire uninstall and re-install of Spectrum may require more efforts.
