What is the "IAC Driver Bus 1"?

When I start Logic, I get a message that reads:

"Instrument "IAC Driver Bus 1" sends to a MIDI port named "Bus 1" of MIDI interface "IAC Driver" which no longer exists."

What the heck is this?!  How do I correct the problem?

IAC Driver is a default MIDI Device in the Audio MIDI Setup utility (/Applications/Utilities). It lets you route MIDI messages between Application that supports that protocol. Hence the name IAC, Inter-Application Communication.

Maybe the device is turned off. Double click on the icon and make sure the online checkbox is enabled

Hope that helps
