This is an artifact of using i1Match 3.6.2 software with the Mac OS X (Snow Leopard 10.6).
Users of the i1Display2 and i1 devices that build their monitor profiles with i1Match may experience a message on restart that the computer has no active monitor profile and one needs to be created.
When checking for the profile in System Preferences > Displays > Color, the profile actually is there and is being applied. The workaround solution for this issue, that has began with Snow Leopard Mac 10.6, is to build a monitor profile, but deselect the checkmark in the box to the left of "Activate reminder for the monitor calibration".
Now you can select a valid monitor profile, restart your Mac and confirm that the computer no longer gives you this error message.
