The search dialog appears, but when I search anything, doesn´t find nothing... the resulte of the search, are always ZERO!!!!..

Please Help!!!..

PS: My Directory Opus version is, I tried to reinstall Dopus, but the problem is still here...

Check and double-check everything in the search criteria. Chances are you are just excluding everything due to something left-over in one of the boxes.
