Help me with SWF Text and Navigation

Hello I am wondering how I edit SWFs text for example changing Screenshot by Lightshot (Activity Points) into 'Motto: {motto}'
I also would like to know how I change where the button takes you for example making it so Screenshot by Lightshot (Catalogue Button) takes you to create a room.

I only need to know where I change them. Thank you.

Also does anyone know where to find this so I can remove it: http://prntscr.com/grkhet
And this: Screenshot by Lightshot

Thank you everyone who helps me here, may god bless.

Rabdcasm and habbo UI editor would be all the tools needed but i can't really help much more.
