OK, if you are still having this issue and haven't had any luck after clearing your browser cache, please try this.
Click on or anywhere around the theme logo snowman area, that area is a hotlink (hyperlink) which will take you to the site's home page.
In the address bar of your browser you will see the address of the site ending with a forward slash and two letters representing the language code and then another forward slash. Russian will end /ru/ English will end /en/ . Simply edit the two letters between those two forward slashes to the language designation you want and hit enter. See if that does the trick for you.
