Problems extracting Longest Flowpath in HEC-GeoHMS

[Jorge_Figueirade_Sousa]

Hello

I'm making a hydrologic study using Arc Hydro and HEC-GeoHMS.

In HEC-GeoHMS in the Menu Characteristics, when i try to extract the Longest Flowpath it always appears this error message and i can't move forward on my project.

Is there anyone who can help me, please!

Thanks in advance.
