Body: <p>We've recently installed CiviCRM 4.6.6 and we're on WordPress 4.3. I've got a major problem with CiviMail (see <a href="https://civicrm.stackexchange.com/questions/5182/civimail-new-mailing-no-recipients-error">HERE</a>. No one has responded in six days. Is there backwards compatibility? Would it be safe to install 4.5.8?? At this point, we're just using the Contact table. I'd rather not import all the data again, since I could only do 600 records at a time (the command line doesn't support groups or dup checking). I've got to get this fixed...someone please help me!! thanks...jim</p>
