We tried everything to fix it and the only way we have found is to completely remove crm and reinstall it to a pre roll up 4 version :-(</p> <p>There are support calls to Microsoft regarding this.</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10218544" width="1" height="1">
