HEC-HMS optimization trial problem.

Hello!

I am using HEC-HMS 4.1 for simulating a daily two-years period.
Simulation Info:

Basin:
I have one basin. Loss = Soil Moisture Accounting, Transform = unit Hydrograph, no baseflow.

Meteorological setting: Precipitation = Gage weights

My main question is about optimization of the loss method parameters, I change all of them, but there is no significant variation in the outflow hydrograph except impervious parameter.
I even use optimization trial to find the best value for each parameter, but the process bar jumps to finish after 40 percent, and when I check the optimization results, the optimized values are equal to initial values. Is there any solution for this problem?

I will appreciate if someone helps me.

Many Thanks
Javanamrd.
