>>2511428relax there buddy, let me see if I can help you out with a small little tip when it comes to loading motions
on the left side of the MMD client you're gonna see a lot dots and lines.
If the dots are red then press the delete button on your keyboard, it should delete everything the motion had loaded
If the dots are not red but white instead.
Make sure you scroll all the way to the start of the motion. if the number is 0 (look at the image related)
then you can load the same motion again and press delete after its done loading
