Errm there's a thread about this somewhere (I'll look). Dan Dare and I (and possibly others) did the same, after noticing that we could. It only seemed to extend dates. Elvis then advised 'cleaning' our installation with a special tool which he provided via the Helpdesk. I used the tool and all was back to previous state. To be honest I'm not sure what demons you may have awoken (if any), but let me find the thread...
