Reply To: Form: 'Please enter a correct Email' not translated

well you said nothing about uploading the .mo file, I had just uploaded the .po file as I never really knew how these worked!
ok so editing the .po file and uploading the .mo file fixes it.
oddly enough, the .po file did have the text translated correctly. I guess the .mo file was just outdated in relation to the .po file

thanks!
