Parallel processing not working

Dear Yang;
First of all thank you for the code. I have been trying to get your code to work for some days now but all my attempts to start parpool have failed. I have googled and tried everything. As this the error encountered by a number of Matlab Users, would you recommend running the code without parallel processing?

The information about my System is.
Core m y510c CPU @ .8GHz 1GHz.
Win 8.1
MATLAB Version: 8.3.0.532 (R2014a)

Error is:
> Error using parpool (line 111)
> Failed to start a parallel pool. (For information in addition to the causing error, validate the profile 'LocalProfile1' in the
> Cluster Profile Manager.)
>
> Error in train_model (line 31)
> parpool(4);
