Amazingly quick Wolfrug.
Yes i did use that tool, and only recently to so that would make sense. I didn't even consider the fact it may have deleted something it should not have, bugger.
In that case the reinstall seems like the way to go (unfortuantely). I'll post back.
Hopefully this will help someone else. Out of interest has this been a problem others have experienced with the beta removal tool, as i couldn't find much info on the forum.
thanks again Wolfrug Â
