Error: Exit Code = 157

Hello guys,
I am having trouble with internal boundary condition in Hec-Ras 5.0.5 and 2d flow simulation.
I have drawn an internal boundary and typed a flow hydrograph of a constant negative flow (outlet of a river) throughout my precipitation duration.
When i run the Unsteady flow analysis i am getting this error.
If i delete the internal boundary everything runs correctly without errors.
It would be nice to have the internal option and not having to break the 2d flow area and insert a external BC for this situation.

Regards

Well i saw that if i insert positive values the simulation runs.
I am guessing we cannot give negative values in internal BC?
