script editor problems

im still having problems with the script editor, i retrieved my password but now i cant get past the first page. when i select create a script, it says i already have one, so i tried to edit it by adding my forum addy and password and then it comes up that the addy doesnt exist.
im trying to get in and put a texture on my site , can anyone tell me what im doing wrong plz. when i first tried the script editor i added a background picture from my pc but didnt like the way it looked so i deleted it, has this got anything to do with it ?
thanks in advance guys xxx

When you tried to edit it, have you checked what I circled with purple ?

Hello.

What do you in "script name" ?

You must put the address of your board without the http://, www. and /index.forum
