    Hi there,

     
    I’m interested in purchasing your software (running your trial versions at the moment) but can’t get the following error resolved.
     
    Please could you assist me in resolving this error?
     
    I get this error when trying to run a walk forward optimization matrix.
     
    I’ve also attached the log file for your reference.
