Need help resolving license issue

I’ve been using Avast 4.8 on my home computers for a couple of years, and on my Windows Home Server computer as well. Recently, my home computers started alerting me that my subscription was about to run out (true), so I used the functionality built into the client to buy a new 2 year license for 3 computers, expecting that I’d get a license for version 4.8. The license file delivered is for Avast 5.0 however, and can’t be installed in Avast 4.8. Over a week ago, I submitted a support ticket describing the situation and mentioning that as I have and use Avast for Windows Home Server as well, I need to keep 4.8 on my home computers for compatibility reasons. 5 business days (effectively a full week) after my initial request, I received a reply telling me I should stay with Avast 4.8. No further help has been forthcoming.

So my question is: What do I have to do to get this resolved?

Try contacting sales (at) avast (dot) com and see if you can get them to send the 4.8 license file.

The latest version of 5.0.462, just released today I believe is able to communicate with WHS http://forum.avast.com/index.php?topic=56770.0

So that may be an option, something you can talk to sales about anyway.
