I am back. I just noticed something strange with the autopurge. It was/is set on the standard 120 days and I did always notice that after the option box the purge date was always incorrect just a few days away.
Now is says Next purge is scheduled on June 28, 2011, 13:56
I noticed most stats where gone and that was around the time of the previous purge (about 1 hour ago I guess).
I got all the stats back just by re-saving the config, but my guess is that later today it will be purge again.
Whatever I try the date will not go any further then well today.
I have created the same admin access as before if you need it.
