APERATURE PUT ALL PHOTOS IN Trash, how to put backcountry

Somehow Aperature put all my photos in trash.

There are about 20K images. I want to move them back to their original places/folderS/projects etc. BUT it only let's you do 1 at a time. I cannot drag all 20K images nor highlight and then click the "Put Back" feature....only 1 image at a time. So this would take about 5 months to do.

There must be a way to restore it like before.

I've also clicked the Restore feature but that didn't do anything.

Thanks
