HEC-HMS Error 10000

[LYP]

Hi

I'm working with HEC-HMS 3.2 and attempting to enter time-series data for a precipitation gauge. However, the table option which would allow the user to enter data manually cannot be activated when the required time window is selected. On trying to attach a DSS file instead and run a simulation, the following error is created.

ERROR 10000: Unknown exception or error; restart HEC-HMS to continue working. Contact HEC for assistance.

Also, once the Time-Series Data component is selected, other components cannot be accessed again unless the program is closed and re-opened.

Does anyone have any suggestions?

Thanks
