I'm paying for my creative cloud (student version) and my after fx trial version is over but it keeps asking me for the serial number. What can i do?

Moving this discussion to the Creative Cloud Download & Install forum.

Anebz I would recommend fixing the connection error preventing the applications from contacting our activation server.  You can find details on how to resolve the connection error at Sign in, activation, or connection errors | CC, CS6, CS5.5 - http://helpx.adobe.com/x-productkb/policy-pricing/activation-network-issues.html.
