MP - 01 problem

I recently purchased my MP-01.
Couple days later while i was transforming the right leg came off the waist joint.
I try putting it back in but it the leg keeps falling out.
I dont know if i have broken or snapped any piece off the joint.
Is there anyway to fix this or is it broken forever?
