Translation not working in frontend

Hi.
I made translation for the plugin into russian language
Everything works in backend, except string with event details From –____– to –____–
I added these values in corresponding language files, but plugin seems to ignore these values, and still shows english equivalent.
Please help resolve this issue.
Regards, Vadim

p.s. Also I would like to contribute with my translation. Please let me know where I can send .po and .mo files with translation to russian language, so that this language can be available from the box.
