Menu language - Can't edit some

Hi all, I was just wondering what would make some of the language files unchangeabel and some are. I have been trying to edit my menu to give it a little color and noticed that I cant change some of them through the language file system. I am also having problems with the Available Membership Types wording in top heading not being able to edit. Would like to ad All are one time payments. When I change these it says it is edited successfully but it isn't. I know I have the right ones and the code is correct. Is there a place in the data base for these as well. Tried altering the language file itself but that didn't work so I guess it is a database permission possibly. I think. Still new to this but I think I'm catching on.

just bumpin this. Hope you guys don't mind me doing this in this forum

All color changes should be done via the CSS files and NOT via the Language Keys.  You'll get a lot better results using the CSS and it'll got a whole lot faster.

Ok, that makes sence. I just saw this as a short cut. Can you tell me which file it is to edit this?

First:  Return all your language keys as they were.  It was a very industrious item on your part.

Second:  Use firefox w/the firebug add-on and it will show you where to change the CSS for just about anything. 

To help you along, there are 115 incidents of menu in the templates/base/css/general.css file.  Use firebug to isolate out exactly which strings you want out of there.
