ERROR 544: Precipitation time series error

[Anonymous]

I have been using Stormwater to  model site drainage.  I had both 10 year and 100 year storm time series as user definied time series data.  After I switched between 10 year and 100 year time series data a few times to adjust the model, now when there is problem in the result.  Even though I selected 100year time series with higher rainfall intensity, the calculated results were already shown for 10 year time series data.  

I tried to deleted all the 10 year time series data from the model, then when I run the model, an error message showed up " ERROR 544 : Unable to perform analysis,  precipitation time series does not exist."   But the 100 year time series data WAS in the model.   Please help.

Thanks!
