Translation of directory listing

Hi i used 3.5 hour first translate this plugin in normal then a specific change only for my site. But it still shows: "My listings and Signup" on the frontpage.

I have translated: "My Listings" to "Mine Lister" and "Mine Restauranter" and: "Signup" to "Registrer"

In the .po file however it did create a .mo file at the same time should i delete that in the plugin folder?
