I managed to used the backuped module version, but I had really really strange issues on the way. On some versions the whole site only worked when the admin user was logged in, otherwise the site crashed complete. Now I have it worked again, but the calendar entry in topmenu is duplicated, hope I can managed to revert it, but it seems that some obsolete database entries still exists and causing that errors :/

it has worked out now in the new version, but i just could only delete the module, but doesn't matter so far, can be closed.
