The newer tanks have a mechanism to prevent major leaks. If the valve is opened suddenly when the lines are not pressurized, it does not permit gas to flow. Close the tank valves and momentarily open a valve on the stove. Close the valve on the stove. Carefully and very slowly at first, open each tank valve.
This process may (or may not) solve your problem.
