So here's the problem:

I have a low poly model which i modeled using extrude modeling

I am now done with it and I am trying to smooth it.

The Model:





Smooth Settings then I click Apply:



Followed by an error message into maya shutting down

I try it the second way, which is to click smooth from the menu without going into smooth settings>Apply

and it works but my model is messed up:



I am new to Maya and I think the problem in the above picture is a problem with my model so I try to delete the cone thing coming out of the model, but as soon as I try to edit it:



I have tried searching for this error online and I haven't been able to find anything. I really need to get this done by a deadline so any fixes are welcome.

I am assuming this has nothing to do with video card/cpu since mine are relatively new and they are more than fast enough for a simple task like this.

Thank you
