How to save the uv layout?

Hello i have a stupid question, but in my version of blender (2.5.7), when i got to >UV (at the bottom of the uv image editor) I cant find the >export uv layout< button. Where is it?

File / User Preferences / Addons / Import-Export, activate UV Layout

This question has been asked multiple times, the forum search is there for a reason.

It worked! Thanks a lot ! (:
