I've talked to a few coleagues and they say some packages may have not been upgraded for some reason and I should look into your installation. For that, you need to enable Remote Assistance. To do that, go to your Core's Pluto Admin website, Wizard -> Security-> Outside Access and tick the "Allow Pluto tech support temporary access using this password" checkbox, enter and confirm a password, and then private message me your installation number and the password you typed so I can connect to your machine and see what went wrong. You can also e-mail me these details to radu_dot_c_at_plutohome_dot_com
