Upgrade free trial to paid

Hi Wilhelmina,
For help on this issue please try reinstall AVG according to this article.
Thanks

Have just uipgraded from trial to paid version of AVG Internet Security.  Have restarted, but AVG saying "Firewall cannot start because an  error has occurred in communication with a driver.  Please contact AVG Support".  First, how on earth do you contact AVG support, I followed everything and keep being asked to sign in, created an account and still can´t make contact.  Secondly, has anyone else had the problem of (a) contacting AVG support, and/or (b) had the same problem.  I had no problems with the trial version at all.  I feel it is a very disappointing start to my internet protection association with AVG and wonder if I should just ask for a refund.  Or can anyone tell me just how you can contact Technical Support, because I am pretty tired of trying.  Many thanks for any help or advice you can give,.
