I run "simpleFoam" solver to c
 

I run "simpleFoam" solver to calculate a flow field to step 600. Then I changed the discretization scheme for div(phi, U) from "upwind" to "QUICK". Then I modified "startFrom" entry as "startTime" and set "startTime" as "600" in the "controldict" file, and run "simpleFoam" again. But the following error message appeared as follows:

Can anyone help me out? Thanks in advance!!!
