Do you mean to say that you literally went through all of the files and changed the text yourself to Russian? — This would be very bad because then this means you can never update any theme you’re using.
Or do you mean you used WordPress’s localization method to translate via MO/PO files?

You’re still going to have to put all of your translated strings into Arcadian’s PO file.
