The error is where I run the system it says that certain lines do not have flow, they don’t have direct flow in the upstream manhole because they are manholes and only for turning the system. I've tried on other, older files that I know have been run and I'm running into the same issue. I’ve also tried on other computers and having the same problem. It happens with any file I open that has a manhole with no direct flow into it. How to I let storm sewers know that certain manholes don't have direct incoming flow and ignore them. If I click okay or the X button, it shuts down storm sewers and I have to restart the program.
Thanks in advance for the help!
btw I'm running 2012 version, I've tried with 2013 but I get the same warning, but the program does not shut down.
I've attached the .stm file as a .txt, change the extension back to .stm and it should work.
There are two issues.

You need to look at the model and make sure that your most upstream manhole has flow for each branch. It is completely normal for certain pipes/inlets not to have flow, ie. junction boxes. They will still have a flow rate through the pipe. It should not completly crash the program though.
