I just noticed this thread and wanted to say I'm sorry for your desktop being deleted.
But I would also like to point out that in the documentation and on the paths settings you are warned that the output folder is deleted often and that you should NEVER use the desktop or any other folder you don't want removed.
I even built in provisions for at least helping prevent you from using your desktop, I'm actually suprised that you were able to select your desktop folder.
Ohh, also I completely understand those that don't wish to use it. I obviously code myself and some things I just want to do myself. Which is why I added the export to text file feature in MultiHack. That way you can get the MultiHack file, spit out the text file and do it yourself.
Again, sorry to hear about your problems, but I can only do so much and can't force anyone to read documentation.
