If you stored the catalog in the default location and did not change the name, it should be in the My Catalog folder here (not the folder you have selected):
In that folder, you should have a file named catalog.pse17db. Double-click on it and it should open up in the Organizer.
I'm assuming that you did not create a new catalog when prompted to do so. If you moved or renamed your original catalog, then do a Windows search for the file catalog.pse17db and double-click on each one until you find the correct catalog.
I turned on "show hidden files" ........ seach then found the necessary catalog. Your suggesstion to "double clip" to open organizer worked. I am now back in business. Thanks
I've moved this from the poorly named Community Help forum (which is the forum for issues using the forums) to the Photoshop Elements forum so that proper help can be offered.
