HELP! My Sims won't pose at my own poses

Hello there i have this problem that my sims won't pose at my own poses while they can pose in other creator's poses. my poses appear on the menu list of andrew's player but they don't pose it even if it says that the sim is posing. they just stand there moving their head or just completely just stand still (images for ref)

Note: this is my first time doing poses so i really followed every tutorial i could fine even the basic ones but all of them cause the same problem


(image shows that my sims won't pose at my own poses if it says that the sims is posing)

and this is the pose that they were supposed to pose:



I've been using the latest update of the softwares:
Blender 2.76 ( i tried it on 2.70 but it didn't work as well)
Sims 4 studios 3.1.2.2 (Wishes)
The latest andrew's pose play (the get famous patch)
