Please help me

If you're going to use WhiteRussian, at least use version 0.9, the final release version.  Don't use any of the release candidate versions.

Upgrade to 0.9, and see if you still have issues.

Is it so? old version will not work?

Older versions MAY work, depending on your needs.  But as the final release, 0.9 is more bug free than any prior version, so if you're having issues and asking for help, at least be on the most current version possible, as more folks will be able to assist with any issues.
