Melicia:
You might be reaching the limit of your license for StormNET. StormNET is licensed on the number of inlets and nodes.
If your model is larger than the number you have licensed, you can either breack your model into pieces and then use the outflow from one model as the inflow into another. However, this can get somewhat cumbersome after a while.
The alternative is to either simplify your network further or purchase the next larger version of StormNET. Note that you are "credited" with your current license, so it is not like you have to purchase the software all over again.
Please let me know if you need any further assistance with your model.
Sincerely,
Chris Maeder, M.S., P.E.
