Replace skeleton always crash

Hello,

I’ve bought something with animations on FAB, and when i want to replace the skeleton with mine as it is explained in the tutorial, unreal crash all the time

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000018

i can’t do anything, all the things i try about it makes unreal crash, this is crazy, how can i do thos ? Thanks !

Found solution by myself ! Bye !!

kidding, so i first retargeted the ANIMATION BLUEPRINT, then i pressed stop in the animation just in case, then retargeted all the ANIMATIONS, then all the MONTAGES and then finally all the blendspaces. Only way i got it to work without crash.
