Bill -
Your file runs okay for me (I substituted my own rainfall file; you should check yours is okay using COMBINE).
Suggestions -
1) change your B2 line to 1 1 0. That will reduce the number of printouts in the output file, one of which may be the problem in your SWMM version
2) download the latest SWMM.EXE from
www.ccee.orst.edu/swmm
3) you have F0<Fc for your soils parameters. This could blow up some versions of Runoff, as it doesn't make a lot of sense. F0 is typically a few inches per hour.
