Invalid Subscription

Hello.

I just purchased Avast Premier, installed it and have been hit with the ‘You are Not Protected’ because for some reason my liscence is invalid. What the heck? I upgaded from Avast Internet Security (for which was about to expire in four days). Help please?

Remove the current system from your account.
Perform a clean installation for avast premier and use the license file.
See if that is solving it.

Appreciated
