Converted back to Outlook 2007 from 2010.. really annoying problems. help?

[Teriaki]

I just switched back to Microsoft Office 2007 from 2010 due to issues. Now when I converted back, my Outlook ALWAYS displays this message when I open it.



"The mail profile "Outlook" was created with a newer version of Outlook and might contain information that is not compatible with your current Outlook version. If you experience problems with this profile, you can create a new profile. In Windows Control Panel, open mail, then click Show Profiles, and then click add."

Now I have tried several things:
1. delete my old profile and RE-make it, although it was working perfectly fine.
2. looked through all of my settings.

I CANNOT find a way to turn off this godforsaken message that pops up EVERY FRIGGIN TIME I open Outlook. It drives me nuts, and I would love to find out how to turn this off.

PLEASE help.
