Checking the PUSH checkbox shouldn’t influence the ordinary update check anyhow; it just affects checking for the special e-mails… so, if not registred, is shouldn’t have any effect.
The serial number shouldn’t have any effect either (especially for the demo keys - they are mostly the same).
Is the configuration of the Updates (Connection) the same on all the machines? Or rather, is the connection correctly set?
In the Professional version, you can use the Scheduler to start the update whenever you want (just select Update as the task to be used).
