Soft Body Collistion help

[Khoatic]

So here's my dilemma, Ive been looking and posting for a solution to getting a soft bodied object to obtain collision. Now i came here because i though you guys might be able to help me. I'm using a custom object from 3DS Max 2010 and have the soft body attaches and hows as being a soft body in the preview. Then i export it to UDK and I'm port it there, i adjust the settings and put it in the game. Now comes the problem, when i enter the game it has the soft body motion and what not; however I can't shoot it or walk up and run into it. Id like to be able to shoot it and it jiggles from the force as well when i run up to it. Please help, Ive nearly looked half way across the internet for some kind of answer and i really wanna get this working to put in my level. Any and all help is very much appreciated.
