Someone can help me please with this Hec-GeoHMS 10.1 trouble.

When I try to launch the RiverLength tool or any other tool of the characteristics menu, I get this message: ???RiverLength tool not found. Please add GeoHMS Tools to the toolbox and try again!???. I don't now what it's happened.

GeoHMS is  installed correctly, I used it  for all the Basin Procesing in the same project watershed.
