The error message tells you exactly what the problem is. For example, here is one of the errors:
Error 410: Cannot load file
Unknown item:
ber=9P
in Pond 10P
And here is the corresponding portion of the project file:
[NODE]
Number=10P
Type=Pond
Name=PROPOSED TOTAL DISCHARGE
XYPos=0.125276572601079 1.9630041655851
Message=[40] Hint: Not Described (Outflow=Inflow)
ber=9P ********** this should be "Number=9P" ***********
Type=Pond
Name=EXISTING DISCHARGE
XYPos=0.108910891089109 6.35643564356436
Message=[40] Hint: Not Described (Outflow=Inflow) here is part of your damaged file:
I've marked the line with missing characters. Unfortunately several other lines also seem to be missing before this. All of your errors are similar. As I said before, this suggests a problem with your computer or file system. There is nothing wrong with HydroCAD. But when the files are being opened there is data missing, which indicates a problem with your computer.
Try another PC and you will find that everything works fine.
