Need help with undoing a folder move

I was trying to move tasks from a folder in one workspace to another workspace. It was stating to use a folder to do this. So I created a folder and My Scrum team folder move under the Dev to Projects folder I had created in anticipation of using the cross account copier feature but unfortunately I thought it would copy the items not actually move them. Now I need to get the My scrum team folder from under the Dev to Projects folder. The article said to use the activity log but my folder move is not showing up. HELP!!!
