Unable to Complete Version Check??

[Erella]

Hmm... The same situation here. Worked about 20 minutes before the maintenance and now it can't complete the version check. My provider is also ATT U-verse.

The error is as such:

Unable to complete version check.
[30605][20448][10009][10019]

It looks like someone has had success by changing their IP settings but is there anything else we can do?

I too have AT&T Uverse.

I'm on Windows 7. I went to:
Control Panel/ All Control Panel Items/ Network and Sharing Center.
Toward the top right underneath "View your active networks", look for Connections: Local Area Connection. Left-click and hit "diagnose" on the status window that comes up. I had a problem which it fixed.
This cleared up the issue for me; hope it works for you.
