can't change eqhost login

[darious]

I've tried changing the Login under eqhost multiple times without success. When I installed this on my laptop, with Vista, I had to change the adminstrator. I'm running windows 7 on my main system, but when I alter the eqhost file and try to save, it reports "Access Denied." I've altered the adminstrator to allow me full control and still not able to save the changes, any ideas?? I think I'm at my wits end here, any help would be appreciated!
