Can't empty my trash :(

Hello, So I've only owned my MBP for about 2 months now, my first mac, and I'm still pretty new at everything so I'm not sure if I'm just missing something or doing something wrong but this is my problem.

So I have the file "sixtyforce" stuck in my trash can. It says it is still in use, but as far as I know it isn't at all. I've tried restarting, shutting down for a while and turning it back on, forcing empty and it's still there. So I googled this problem and I found http://www.lancelhoff.com/cant-empty-trash-on-a-mac/ with a solution, But after I follow the directions, open terminal, enter the code, drag "sixtyforce" from my desktop and press enter, it gives me the warning then it says Password: and I CAN'T TYPE ANYTHING AT ALL. I tried it like 20 times.

So I closed terminal, restarted the mac, opened terminal again to try it and now nothing happens AT ALL when I type in cd ~/.Trash && sudo rm -rf , add the files and press enter. Nothing.

This is really frustrating and I can't find any other options to get rid of these files, and the apple support help nothing worked for me in there either. Any help???

 

I just tried sudo rm -r instead and nothing happened.. I mean it's just sitting there like I didn't press enter at all Which sucks because before it was at least doing something, and now that you say the password won't show up to type it anyway, that crossed my mind so i tried and it just repopped up password. I did three times until it stopped me. Unless I don't know what password it's talking about? So I feel like I screwed something up since terminal isn't doing a thing anymore..

 

And GGJStudios when I said nothing worked for me in the apple support I was talking about that page, sorry.
