Did you switch your account page to the Polish language one first? That option is in the middle of the very top line of the page.

You could try an uninstall via Control Panel, then run the cleanup tool - look for MCPR in Useful Links at the top of this page, reboot and then reinstall from the Polish account page.
That's assuming the interface is available in that language which I would assume is OK and Tony is finding out that information for you.
