Character Walks Backward and Can't Use Abilites

That's odd.

It sounds to me like either you have some other software getting in the way (e.g. GHub), or your key bindings in-game got messed up. I would start by looking at your key bindings via the in-game menu. If all looks good there, figure out what other software might be getting in the way.

This post may help as well.

In game options won't let me bind mouse buttons to my abilities, so that's weird as well. I feel like i had this happen some time ago and i was directed to erase my profile somehow, but i can't exactly remember, i do remember being annoyed that i had to reset all of my hero's upgrade cards.  

I have a feeling it’s linked to the recent download of Jedi survivor and in that game I use a controller instead of a mouse and keyboard… so I don’t know, still looking for the culprit.

@Dhuell You are likely on to something. While it very likely does not have to do with Jedi Survivor, it may have to do with your controller. You need to unplug the controller while playing SWBF2 - controller or mouse/keyboard; the game struggles if all are connected.
