I have been network rendering using single computer, all of a sudden I am getting fails on the renders, the renders prepares bit then proceeds no futher , I have no idea what has changed, the only thing that has changed is in the box for network rendering options, the check box for the option of distributing is not available t be checked if that makes sense, I am desperate to complete the renders for a televison series that is going to air, we are in urgent need of a solution.
