Help with no heat?

in THE MAIN WALL
We have a 2 zone forced hot water boiler... baseboards in all rooms... Woke up early Friday with no heat in upstairs zone... Temps below zero suspected freeze in addition as heat stays off when wood stove is lit.. as it was Thursday.... Spent the last 2 days tracing lines and thawing with heat gun/heaters... torpedo heater under addition all lines accessible no freeze.... house temp as at 78 with stove burning and ceramic heaters in rooms... When call for heat sent circ kicks on appears to be trying to circulate but no hot water makes it beyond the circ... System can not be bled, which I have been told signals a clog/freeze... Does anyone have any ideas if it indeed sounds like a freeze or could there be another issue... Thanks in advance for any help... I have been thawing for 3 hours and don't see how anything could possibly be frozen...

    What pressure is your boiler gauge saying? You will need 12psi or so to get any air out. Run the pressure up to 25psi and try bleeding. Also, while pressure is up, isolate the zone and try purging it.
