LEAVE UPSTAIRS MCB OFF and MAKE SURE CIRCUIT
FOR THE UPSTAIRS LIGHTS IS ISOLATED/OFF.
unplug all lamps if u can , and turn off all switches,
two way as well , in alternate position.
check any accessible pendants for short circuiting.
IF U CAN care fully with adequate lighting inspect
cables in the loft for damage and signs of short circuit.
If power can not be restored , then a fault is present
and without the proper test gear that electricians
possess , u will it hard to pinpoint the problem.
AND replacing with a new mcb will not remove the
problem , IF a faulty circuit .
Another reason to call in an elecrician would b 2 check
that the mcb is working correctly to eliminate from
the problem

I agree with BLAKEY1963 and since I know you have been working on your lights from previous posts I wonder what you did to blow it and what you mean by blown. Even with short circuit one does not get many MCB's fail and first question with all power off i.e. at main switch will the MCB reset? When you tried to use it was there any electrical bangs pops or flashes. Although they do fail without a fault else where this is unusual.
There is a time when you must realize one limitations and bit the bullet and get an electrician in however embarrassing it may be. I am not saying you have reached that point but you must consider the safety of yourself and others and only if you are certain you know what you are doing continue.
Mistakes with electricity can be irreversible.

thanks for the heads up reguarding my breaker issue. I checked terminations on pendant, and rewired making sure all wires fit tight and snugly. Reset breaker and everything seems fine. If breaker trips again will call in a pro.
