My developer certifications are not being recognized by Studio, nor is the WWDR certificate. All certs are verified and present in my keychains, but whether the default, System, or login keychains are selected, the refresh button only loads my Distribution certs. Attempting to obtain new copies through Studio's 'Get New' button errors out on the daw.apple.com side as can be seen in the following screen-cap: http://cl.ly/image/0F2c3a1Q0c1y
Here is another screen cap of an attempted deployment to device: http://cl.ly/image/2f2s263m471p (at the end, it goes to the same "Oops!" page as the other).
I have already attempted to uninstall and re-install Appcelerator Studio to no avail.
