Ok, this is caused by the fact that because you have used the module a few times since the upgrade, it has created some "dnn_Reports_Visualizer" settings, so it can't rename the settings from the previous version to that name. To fix this, first run this script to rename the incorrectly created settings:
UPDATE {objectQualifier}TabModuleSettings
SET SettingName = 'old_dnn_Reports_Visualizer'
WHERE SettingName = 'dnn_Reports_Visualizer'
GO
Then re run this script to convert your previous settings to the new format:
UPDATE {objectQualifier}TabModuleSettings
SET SettingName = 'dnn_Reports_Visualizer'
WHERE SettingName = 'dnn_Reports_Renderer'
GO
Finally, assuming everything works correctly, you can then run this script to completely remove the incorrect settings (Don't run this script until you are sure everything is working again):
DELETE FROM {objectQualifier}TabModuleSettings
WHERE SettingName = 'old_dnn_Reports_Visualizer'
My apologies for the complicated workaround, I will work to get this fixed as quickly as possible.
