Folders cannot be opened in Windows Connector mail with Outlook 2007

I installed Windows Connector in Outlook 2007 and got a dialog box saying I successfully set it up. Then I created a Windows Live Hotmail account (or it may have been Windows Live Mail). I know it was created successfully because I got an email in the inbox. But when I tried to open the connector acount in my Outlook 2007 inbox I get a dialog box that said "The set of folders cannot be oopened. The file C:\Users\Mark\AppData\Local\Microsoft\Outlook\mnmrsm_cox.ost is not an offline folder file." If you know what I did wrong and how I can open my Connector account, please post. Thank you.
