Outlook connector is forcing me to upgrade, but won't cooperate.

I have a gmail and two msn email accounts hooked up with Outlook 2007. I am
running Windows 7 Professional which I installed a month ago. gmail hooked
up without a hitch. Using Connector I was finally able to hook up my msn
accounts (I am not an expert computer user). Today when I start Outlook I
get the message:

"To continue accessing your mail using Microsoft Office Outlook, you must
upgrade to the latest version of Outlook connector."

I click Upgrade Now. I follow the steps and it looks like it is installing.
But the next time I start Outlook the same message comes up. I repeated
this three times. I restarted my computer. Then I uninstalled Connector and
downloaded from the MS website and installed. I still get the same message
when I start Outlook.

Also, frequently when asked to enter my password for my msn accounts it is
not recognized.
