zero Force everywhere!!

Hi all,
I had recieved following warrning when modeling load test on board pile. Has anyone an idea what does this mean. Attached inp.file.

regards

warrning:"There is zero FORCE everywhere in the model based on the default criterion. please check the value of the average FORCE during the current iteration to verify that the FORCE is small enough to be treated as zero. if not, please use the solution controls to reset the criterion for zero FORCE."Load-test.inp
