Hallo,
yesterday i need to uninstall AIS for a short time (Win 8 64). I installed it again giving my licence file…it’s all ok apart the fact that now Avast refuses to link to my Avast internet account. It opens a dialog box asking me if I want to connect using my email or a facebook account. I enter the email, press the confirmation button and wait…forever 
All the other functionalities are ok. The previous installation linked to the avast account correctly. Please note I removed old entries in my Avast account. My licence files permits usage on three different pc’s…i’m using it just on two different machines.
