amyway to retrieve my work lost by the Sandbox feature in zoho curator

errror publishing keeps poping up. I filed a support ticket with no response in 12 hours.   every time i press the Publish button I got a "errror publishing". These were minor changes.  Support says 10 hour response but not every day I guess. 

This is a rather useless feature if I have to wait days or weeks  to interrupt my workflow. 


Does everyone rely on the back up and restore feature instead or is that just as unreliable?
