No Builds available

It expires in 90 days. That probably means you have just submitted the build to the appStore ?

Could you show what you have in Xcode > Window > Organizer > Archives ?

Normally, it is available just a few minutes after the build is accepted (you should receive a mail stating that app is available for test).

If nothing occurs in a few hours, you could submit a new build (don't forget to increase build number and eventually the version number (1.0.1).

Note: did you get similar messages to those reported here ? https://developer.apple.com/forums/thread/701330
