Cannot update software with Windows Phone 7 Connector.

I cannot get Windows Phone 7 Connector to download software updates for my HTC Trophy. I unlocked the phone and took it to Europe last year, I returned to the US in January 2012 and the phone has been working fine, but I have not been receiving any software updates. Today I tried to download some apps and discovered that I've missed some updates and I cannot download anything through Marketplace until I fix it. When I try to update the software, I get an error message that tells me that Windows Phone 7 Connector cannot download the updates. I think the problem may have to do with the APN, but other users who have mentioned similar issues after reconnecting an unlocked phone have lost all data connection.
