Hello,

It looks like you ran out of weather.  The program used all the dates in
the LTRA5160.WTH file then looked for the next file which would be called
LTRA5260.WTH.

The most likely reason is you have no "harvest" date for the fallow
crop.  You have the simulation set to harvest the fallow at maturity, but
the fallow crop can never mature.

The way sequence occurs is that one crop can not be planted till the last
crop is done, in this case the fallow crop can never be done.  Try changing
fallow to harvest at a reported date and set the harvest date to a day or
two before you plant the winter wheat.
