Longest Flow Path for Catchments

Preface: This is similar to the post I made in 01/19/2015, except the issue back then was that the newest build was not successfully running the batch subwatershed delineation tool. The newest ArcHydro build fixed this particular issue; however, another issue arose when running the Longest Flow Path for Catchments tool.Christine Dartiguenave has been great in assisting me with these issues and I'm hoping to call upon her guidance, yet again!


When previously running ArcHydro tools, I was able to perform the Longest Flow Path for Catchments (LFPC) tool with ease. Since then, I have noticed that there has been quite a few updates within the last couple of months. The issue that I'm having is that both the Toolbar and Toolbox tool for LFPC error out, where normally it successfully ran (I've kept a control working folder to test the ArcHydro tools). The control working folder that I have, stores the ArcHydro files in the default formats for rasters and shapefiles.


Furthermore, I've cleared out the temp folder, ApUtilities > Additional Utilities > Clean User's Temp Folder. I'm stuck and I wonder if this is something attributed with the new build or if I'm in error.


Any help at all is greatly appreciated!


Here are my environment specs:

Windows 7 Professional 64-bit (6.1, Build 7601)
