The Windows version of Bitcoin Core 0.9.0 introduced a bug which affects data paths that contain non-ASCII characters. These are no longer recognised correctly (it's a new bug, Bitcoin-qt 0.8.* was fine with non-ASCII characters in paths). Since the data directory in Windows is C:\Users\[username]\AppData\Roaming\Bitcoin, the problem on a Russian system is likely to be the user name. My guess is that you have a Russian user name and the program is choking on the data path. Try copying the data directory to a path that contains only Latin letters and then change the path in the options accordingly, and it will probably work.
