doesn't show – not translating

I had WPML working fine but the site was slow so I removed WPML all together. I followed Membership plugin instructions under languages, did the .mo file with Poedit. I have had the file on both locations without success. The site default language is Finnish. I have checked and the po file has the same translations I had with WPML but the site doesn’t pick them up. What am I doing wrong?
