Translation to German

Hey guys,

I’m having some trouble with the translation of the plugin and hope you can help me.

I translated all relevant fields, especially those for the confirmation emails. I uploaded the translated .mo file to the languages folder within the plugin’s directory (saved as woo-rfq-for-woocommerce-de.mo AND woo-rfq-for-woocommerce-de_DE.mo).
Also the language of my WordPress installation is set to German.
But the translations don’t take effect. I don’t know why, but everything’s still displayed in English.

Any suggestions?
