Need help with MBE 2.0 For XP32

Whenever i start a new game the dodge works normally, but it stops working after about 20 seconds, i tried changing to side step and dodge again  and it did nothing, the side step also wasn't working and if i load the initial save file it goes back to working and then stops again. Loading a save file made after it stopped working doesn't make it work either, once it stops working only a save from before it stopped wil "fix it"
