updated avast, paid by credit card and i still get message that i need to update

On April 4, 2012 I paid for avast internet security for 1 pc, 1year. As of this date I still get automatic memmos saying I need to update my avast anti virus. I paid for one year, $19.99 and the detail and payment record you sent me says my expiration date is 2/2013, it should be 4/2013 How do I activate my antivirus??

did you recive a license file in mail ?
did you insert it in the program ?

What Avast1 and version do you have ?

If it says you need to update your Avast! you must have an outdated version.
