A recent AVG and Avast antivirus update is preventing DisplayFusion 9.9 from launching on some systems. If you're running into this issue, please update to the latest DisplayFusion 10.0 Beta.
Test it by selecting the task from the list and clicking "Run" in the right pane. You'll see a new DisplayFusion backup file in the Documents\DisplayFusion Backups folder.
It should include everything. Could you send us a support request through the DisplayFusion Settings > Help > Support Request window and include a settings backup with it?
