I have a problem to install 3.6.2 in a New Hard Disk upgrade

Hi, excuse-me my english is bad, i am from Spain.

The last week, upgrade my HardDisk of 80gb has be upgrade to a new 320GB!! the operation is correctly, my AppleTv work correctly after you restore, and update to a version 2.4. but when I reinstall the ATV has a message to version expiration reminder 3.6.1.

I downloaded version 3.6.2 and the same stick of updates, resetting the ATV does not load the new update, ATV now has no version installed, because I can not install the old 3.6.1 nor the new 3.6.2.

what is the problem? I’m doing wrong?

Thank’s
