That is because you have increased the static pressure in the system to the point that the blower can no longer move the air. Keep all the registers open. If you have an area that has low airflow; first check that the register there is properly sealed to the main duct. In fact it wouldn't hurt to check all of them. Depending on how the duct work is laid out you may be able to add an additional register in the bedroom area.
