VX CLASS CHANGING PROBLEM

I'm using RPG Maker VX, and when I change a character's class the class changes, but the character does not get the abilities of the class it changed do.

Can anyone help me on this, is there a simple fix?

No, that's not it Heisen, but thanks anyways. I figured it out though, apparently VX doesn't add abilities when changing classes through events... so I ended up having to make the character learn and forget abilities, manually, along with the class change.
