My Mine-Imator animation buttons doesn't work :/ please help

[Xv_Animations 1]

I was using the old version of this software and this feature was working, but it has been a while since I updated the software and the 2 buttons that were at the bottom of the screen and run the walking and running animations no longer work.
I use a rig that I made myself.

Next, I will make a video so that you can understand it better. If you understand the problem, I would be grateful if you could help me.

i guess you have already applied those animations to a keyframe before it you can try using external running or walking animations 

 

here are some links of external animations - https://www.mineimatorforums.com/index.php?/topic/89580-new-mine-imator-walking-animation/

to use them -

1.  select your skin on timeline (1st keyframe)
2. go to import assets and import this keyframe file which you have downloaded
