The Initial Bug 6 was Fixxed - This here now documents a known limitation =>
Autostart will break and produce erros from Windows on startup when you:
-Edit the Autostart Registrykey located at "HKCU\Software\Microsoft\Windows\Run\Winbackupper_Autostart" and Shutdown Windows before restarting the Backup Software.
This is because the Software checks on startup if the Key is still valid - if not it corrects the error. But in above described case it does not have a chance to do that - therefore the Run Registry key could point to an invalid place - which will then prouce an error on startup!
