Due to changes in render software architecture, a mechanism called JobObject which is used by the Qube! worker disrupts the internal code in common renderers such as 3dsmax and AfterEffects. The worker must be notified not to use the JobObject. To do this, specify the disable_windows_job_object flag when submitting your jobs
ex. qbsub --flags disable_windows_job_object MyRenderer scene.ma
