All meta tags are gone even though they are in database

I've just updated the module from version 6.x-1.0 to 6.x-1.1 and lost all my nodewords even though they are still in database (nodewords table). I couldn't even change the settings, because eveything on setting page was disabled (except of last four options - global meta tags, etc.). I tried to update to 6.x-1.2, nothing changed, after that I tried 6.x-1.3-beta5. With the last one I could change the settings, but unfortunately all my nodewords are still gone. Plus I don't know how to change the meta tags for views now...

Any suggestions?
