You loaded the wrong version of the desktop manager. Delete the desktop manager and reinstall when it comes to intergration options make sure you select blackberry internet service. Delete the desktop servicebook and then re sync should work fine after that. The reason your getting those emails is because you installed the bes and redirector desktop manager.
