'The ribbon doesn't have any tabs or panels currently loaded'.
I was trying to reload (menuload) some blocks from a vendor, when for whatever reason, I lost my entire ribbon, maybe I accidently repathed it or something, by hitting menu rather then menuload.
But now I'm going through it, I have some standard icons reloaded, but they're not part of the ribbon itself. I'm going to have to switch to Autodesk Mechanical to wrap things up. This issue is occuring with Autodesk Architectural 2012.
