I found out a reliable solution for this problem.

firstly I am using ArcMAP 10.1, ArcHydrotool 10.1 and HECGEOHMS 10.1. ( Remember to keep all versions same).

create a folder for your work in c drive and create arcmap folder there.

import your dem to that folder prior to work

start by projecting your dem to UTM projections and IS units.

add projected dem to arcmap. Activate HECGEOHMS and archydrotools from customise >tool bars.

very imp step: click on app utilities in archydrotool box , and set for hecgeohms utility as ( choose correct folder pathway for Easter and vector files to be saved throughout the work) ( in raster : eg : c\desktop\mywork\Layers))

If layers is not came default , just type and save it. 
for vector mywork.gdb will come automatically

then save it .

now before each step of HECGEOHMS, check in data management section to confirm all the fields.

If you have only projected dem , you can add that dem to layer folder created while hydro raster generations and then proceed

I had the same error. I was using projected dem for the hydro analysis but for setting up a new project you need to add original dem with original coordinate data set. After adding original dem to current layer view, Change raw dem to newly added original dem in data management under project setup. And then proceed to generate project.

though my error got solved , while creating new project layer raster layers extracted are not getting added.
