Problem with parallel computing

Dear;

This is the first time I use parfor loop and I trying to run a program on my local computer when I run the program matlab says:

        Error in parallel_function>iMakeRemoteParfor (line 1060)
        P = distcomp.remoteparfor(pool, W, @make_channel, parfor_C);

        Error in parallel_function (line 444)
        [P, W] = iMakeRemoteParfor(pool, W, parfor_C);

What am I doing wrong? I previously run the validate tool on the Cluster Profile mamager and every status has been passed

Thanks

Is that the entire message? Does it not tell you what error it thinks has occurred?
